The importance of the PhD defence reverberates throughout the academic landscape. It is not just a capstone event; it is the juncture where academic rigour meets real-world application. The defence is the litmus test of a researcher’s ability to articulate, defend, and contextualize their work—an evaluation that extends beyond the pages of a dissertation.

Beyond its evaluative nature, the defence serves as a rite of passage, validating the years of dedication, perseverance, and intellectual rigour invested in the research endeavour. Success in the defence is a testament to the candidate’s mastery of their subject matter and the originality and impact of their contributions to the academic community.

Furthermore, a successful defence paves the way for future contributions, positioning the scholar as a recognized authority in their field. The defence is not just an endpoint; it is a launchpad, propelling researchers into the next phase of their academic journey as they continue to shape and redefine the boundaries of knowledge.

In essence, the PhD defence is more than a ceremonial checkpoint—it is a transformative experience that validates the intellectual journey, underscores the significance of scholarly contributions, and sets the stage for a continued legacy of academic excellence. As we navigate the intricacies of this process, we invite you to explore the multifaceted dimensions that make the PhD defence an indispensable chapter in the narrative of academic achievement.

What is a PhD Defence?

At its core, a PhD defence is a rigorous and comprehensive examination that marks the culmination of a doctoral candidate’s research journey. It is an essential component of the doctoral process in which the candidate is required to defend their dissertation before a committee of experts in the field. The defence serves multiple purposes, acting as both a showcase of the candidate’s work and an evaluative measure of their understanding, critical thinking, and contributions to the academic domain.

The primary goals of a PhD defence include:

• Presentation of Research: The candidate presents the key findings, methodology, and significance of their research.
• Demonstration of Mastery: The defence assesses the candidate’s depth of understanding, mastery of the subject matter, and ability to engage in scholarly discourse.
• Critical Examination: Committee members rigorously question the candidate, challenging assumptions, testing methodologies, and probing the boundaries of the research.
• Validation of Originality: The defence validates the originality and contribution of the candidate’s work to the existing body of knowledge.

The PhD defence often takes the form of an oral examination, commonly referred to as the viva voce. This oral component adds a dynamic and interactive dimension to the evaluation process. Key elements of the oral examination include:

• Presentation: The candidate typically begins with a formal presentation, summarizing the dissertation’s main components, methodology, and findings. This presentation is an opportunity to showcase the significance and novelty of the research.
• Questioning and Discussion: Following the presentation, the candidate engages in a thorough questioning session with the examination committee. Committee members explore various aspects of the research, challenging the candidates to articulate their rationale, defend their conclusions, and respond to critiques.
• Defence of Methodology: The candidate is often required to defend the chosen research methodology, demonstrating its appropriateness, rigour, and contribution to the field.
• Evaluation of Contributions: Committee members assess the originality and impact of the candidate’s contributions to the academic discipline, seeking to understand how the research advances existing knowledge.

The oral examination is not a mere formality; it is a dynamic exchange that tests the candidate’s intellectual acumen, research skills, and capacity to contribute meaningfully to the scholarly community.

In essence, the PhD defence is a comprehensive and interactive evaluation that encapsulates the essence of a candidate’s research journey, demanding a synthesis of knowledge, clarity of expression, and the ability to navigate the complexities of academic inquiry. As we delve into the specifics of the defence process, we will unravel the layers of preparation and skill required to navigate this transformative academic milestone.

How Long is a PhD Defence?

The duration of a PhD defence can vary widely, but it typically ranges from two to three hours. This time frame encompasses the candidate’s presentation of their research, questioning and discussions with the examination committee, and any additional deliberations or decisions by the committee. However, it’s essential to note that this is a general guideline, and actual defence durations may vary based on numerous factors.

• Sciences and Engineering: Defenses in these fields might lean towards the shorter end of the spectrum, often around two hours. The focus is often on the methodology, results, and technical aspects.
• Humanities and Social Sciences: Given the theoretical and interpretive nature of research in these fields, defences might extend closer to three hours or more. Discussions may delve into philosophical underpinnings and nuanced interpretations.
• Simple vs. Complex Studies: The complexity of the research itself plays a role. Elaborate experiments, extensive datasets, or intricate theoretical frameworks may necessitate a more extended defence.
• Number of Committee Members: A larger committee or one with diverse expertise may lead to more extensive discussions and varied perspectives, potentially elongating the defence.
• Committee Engagement: The level of engagement and probing by committee members can influence the overall duration. In-depth discussions or debates may extend the defence time.
• Cultural Norms: In some countries, the oral defence might be more ceremonial, with less emphasis on intense questioning. In others, a rigorous and extended defence might be the norm.
• Evaluation Practices: Different academic systems have varying evaluation criteria, which can impact the duration of the defence.
• Institutional Guidelines: Some institutions may have specific guidelines on defence durations, influencing the overall time allotted for the process.

Candidates should be well-prepared for a defence of any duration. Adequate preparation not only involves a concise presentation of the research but also anticipates potential questions and engages in thoughtful discussions. Additionally, candidates should be flexible and responsive to the dynamics of the defense, adapting to the pace set by the committee.

Success Factors in a PhD Defence

• Successful defence begins with a deep and comprehensive understanding of the research. Candidates should be well-versed in every aspect of their study, from the theoretical framework to the methodology and findings.
• Thorough preparation involves anticipating potential questions from the examination committee. Candidates should consider the strengths and limitations of their research and be ready to address queries related to methodology, data analysis, and theoretical underpinnings.
• Conducting mock defences with peers or mentors can be invaluable. It helps refine the presentation, exposes potential areas of weakness, and provides an opportunity to practice responding to challenging questions.
• Actively listen to questions without interruption. Understanding the nuances of each question is crucial for providing precise and relevant responses.
• Responses should be clear, concise, and directly address the question. Avoid unnecessary jargon, and strive to convey complex concepts in a manner that is accessible to the entire committee.
• It’s acceptable not to have all the answers. If faced with a question that stumps you, acknowledge it honestly. Expressing a willingness to explore the topic further demonstrates intellectual humility.
• Use questions as opportunities to reinforce key messages from the research. Skillfully link responses back to the core contributions of the study, emphasizing its significance.
• Rehearse the presentation multiple times to build familiarity with the material. This enhances confidence, reduces nervousness, and ensures a smooth and engaging delivery.
• Maintain confident and open body language. Stand tall, make eye contact, and use gestures judiciously. A composed demeanour contributes to a positive impression.
• Acknowledge and manage nervousness. It’s natural to feel some anxiety, but channelling that energy into enthusiasm for presenting your research can turn nervousness into a positive force.
• Engage with the committee through a dynamic and interactive presentation. Invite questions during the presentation to create a more conversational atmosphere.
• Utilize visual aids effectively. Slides or other visual elements should complement the spoken presentation, reinforcing key points without overwhelming the audience.
• View the defence not only as an evaluation but also as an opportunity for continuous improvement. Feedback received during the defence can inform future research endeavours and scholarly pursuits.

In essence, success in a PhD defence hinges on meticulous preparation, adept handling of questions, and projecting confidence and composure during the presentation. A well-prepared and resilient candidate is better positioned to navigate the challenges of the defence, transforming it from a moment of evaluation into an affirmation of scholarly achievement.

Failure in PhD Defence

• While the prospect of failing a PhD defence is relatively rare, it’s essential for candidates to acknowledge that the possibility exists. Understanding this reality can motivate diligent preparation and a proactive approach to mitigate potential risks.
• Failure, if it occurs, should be seen as a learning opportunity rather than a definitive endpoint. It may highlight areas for improvement and offer insights into refining the research and presentation.
• Lack of thorough preparation, including a weak grasp of the research content, inadequate rehearsal, and failure to anticipate potential questions, can contribute to failure.
• Inability to effectively defend the chosen research methodology, including justifying its appropriateness and demonstrating its rigour, can be a critical factor.
• Failing to clearly articulate the original contributions of the research and its significance to the field may lead to a negative assessment.
• Responding defensively to questions, exhibiting a lack of openness to critique, or being unwilling to acknowledge limitations can impact the overall impression.
• Inability to address committee concerns or incorporate constructive feedback received during the defense may contribute to a negative outcome.
• Comprehensive preparation is the cornerstone of success. Candidates should dedicate ample time to understanding every facet of their research, conducting mock defences, and seeking feedback.
• Identify potential weaknesses in the research and address them proactively. Being aware of limitations and articulating plans for addressing them in future work demonstrates foresight.
• Engage with mentors, peers, or advisors before the defence. Solicit constructive feedback on both the content and delivery of the presentation to refine and strengthen the defence.
• Develop strategies to manage stress and nervousness. Techniques such as mindfulness, deep breathing, or visualization can be effective in maintaining composure during the defence.
• Conduct a pre-defense review of all materials, ensuring that the presentation aligns with the dissertation and that visual aids are clear and supportive.
• Approach the defence with an open and reflective attitude. Embrace critique as an opportunity for improvement rather than as a personal affront.
• Clarify expectations with the examination committee beforehand. Understanding the committee’s focus areas and preferences can guide preparation efforts.
• In the event of failure, candidates should approach the situation with resilience. Seek feedback from the committee, understand the reasons for the outcome, and use the experience as a springboard for improvement.

In summary, while the prospect of failing a PhD defence is uncommon, acknowledging its possibility and taking proactive steps to mitigate risks are crucial elements of a well-rounded defence strategy. By addressing common failure factors through thorough preparation, openness to critique, and a resilient attitude, candidates can increase their chances of a successful defence outcome.

PhD Defense or Defence?

• The choice between “defense” and “defence” is primarily a matter of British English versus American English spelling conventions. “Defense” is the preferred spelling in American English, while “defence” is the British English spelling.
• In the global academic community, both spellings are generally understood and accepted. However, the choice of spelling may be influenced by the academic institution’s language conventions or the preferences of individual scholars.
• Academic institutions may have specific guidelines regarding language conventions, and candidates are often expected to adhere to the institution’s preferred spelling.
• Candidates may also consider the preferences of their advisors or committee members. If there is a consistent spelling convention used within the academic department, it is advisable to align with those preferences.
• Consideration should be given to the spelling conventions of scholarly journals in the candidate’s field. If intending to publish research stemming from the dissertation, aligning with the conventions of target journals is prudent.
• If the defense presentation or dissertation will be shared with an international audience, using a more universally recognized spelling (such as “defense”) may be preferred to ensure clarity and accessibility.
• Regardless of the chosen spelling, it’s crucial to maintain consistency throughout the document. Mixing spellings can distract from the content and may be perceived as an oversight.
• In oral presentations and written correspondence related to the defence, including emails, it’s advisable to maintain consistency with the chosen spelling to present a professional and polished image.
• Recognizing that language conventions can vary, candidates should approach the choice of spelling with flexibility. Being adaptable to the preferences of the academic context and demonstrating an awareness of regional variations reflects a nuanced understanding of language usage.
• With the increasing globalization of academia, an awareness of language variations becomes essential. Scholars often collaborate across borders, and an inclusive approach to language conventions contributes to effective communication and collaboration.

In summary, the choice between “PhD defense” and “PhD defence” boils down to regional language conventions and institutional preferences. Maintaining consistency, being mindful of the target audience, and adapting to the expectations of the academic community contribute to a polished and professional presentation, whether in written documents or oral defences.

Is PhD Defense a Formality?

• While the PhD defence is a structured and ritualistic event, it is far from being a mere formality. It is a critical and substantive part of the doctoral journey, designed to rigorously evaluate the candidate’s research contributions, understanding of the field, and ability to engage in scholarly discourse.
• The defence is not a checkbox to be marked but rather a dynamic process where the candidate’s research is evaluated for its scholarly merit. The committee scrutinizes the originality, significance, and methodology of the research, aiming to ensure it meets the standards of advanced academic work.
• Far from a passive or purely ceremonial event, the defence involves active engagement between the candidate and the examination committee. Questions, discussions, and debates are integral components that enrich the scholarly exchange during the defence.
• The defence serves as a platform for the candidate to demonstrate the originality of their research. Committee members assess the novelty of the contributions, ensuring that the work adds value to the existing body of knowledge.
• Beyond the content, the defence evaluates the methodological rigour of the research. Committee members assess whether the chosen methodology is appropriate, well-executed, and contributes to the validity of the findings.
• Successful completion of the defence affirms the candidate’s ability to contribute meaningfully to the academic discourse in their field. It is an endorsement of the candidate’s position as a knowledgeable and respected scholar.
• The defence process acts as a quality assurance mechanism in academia. It ensures that individuals awarded a doctoral degree have undergone a thorough and rigorous evaluation, upholding the standards of excellence in research and scholarly inquiry.
• Institutions have specific criteria and standards for awarding a PhD. The defence process aligns with these institutional and academic standards, providing a consistent and transparent mechanism for evaluating candidates.

Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

If you want to learn more about dissertations in your own discipline, don’t hesitate to reach out to graduates from your program and ask them about their experiences.

How to prepare an excellent thesis defense

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

• Avoid popular and eminent faculty member
• Choose the one you know very well and can approach whenever you need them
• A faculty member whom you can learn from is apt.
• Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Your Dissertation Defense

4-minute read

• 1st August 2023

After years of research and study, you’ve finally reached the grand finale of your PhD years: your dissertation defense. Since defending your dissertation is the culmination of all your hard work, it’s essential to do everything you can to prepare for it.

In this post, we’ll take you through how to ready yourself for your dissertation defense so you can focus on your accomplishments and excel during this crucial professional moment.

What is a Dissertation Defense? 

The dissertation defense is the crowning moment of years of research – the final examination before a PhD student is awarded their doctoral degree.

During a dissertation defense, the student presents their research, methodology, findings, and conclusions to a committee of faculty members and experts in their field. The committee then engages in a question-and-answer session to assess the student’s understanding of the subject matter, the quality of their research, and their ability to defend their work under scrutiny.

Many PhD students consider it to be the defining moment of their academic career and their chance to prove their expertise in their chosen research field.

If all this sounds overwhelming – don’t worry. If you’re a PhD student, you’ll have plenty of time and opportunity to adequately prepare for your dissertation defense. Below are some strategies to help you get ready for this significant occasion in your career.

1.   Know the Requirements

Familiarize yourself with your institution’s guidelines and requirements for the defense process. Understanding the format, time limit, and expectations for the presentation will help you to prepare your material and anticipate any issues.

2.   Review Your Dissertation

Even if you think you know it inside and out, review your dissertation from beginning to end. It may have been some time since you’ve last read and considered certain portions of your research and findings. Consider what your committee might ask about your research questions , data analysis, and conclusions.

3.   Work on Starting Strong

To begin your defense on a strong note, work on creating a clear and engaging introduction. You can start by briefly outlining the purpose of your study, research questions, and methodology . Try to stay on topic and don’t veer off track by discussing unrelated or unnecessary information.

4.   Practice Presenting

Practice your presentation skills by rehearsing your defense multiple times. Focus on clarity and pacing and try to stay within the allotted time limit. It also helps to record yourself so that you can see yourself from your audience’s point of view.

5.   Practice Q&A Sessions

To build your confidence, enlist friends and colleagues to conduct mock question-and-answer sessions. When practicing, remember to pause before answering questions you’re unsure of. It’s better to take your time delivering a response than it is to give an inaccurate or incorrect answer.

6.   Seek Feedback

Find out if your institution offers mock defense sessions where peers or mentors play the role of the committee, ask you questions, and give feedback . You can also have colleagues, mentors, or advisors review your presentation and offer practical feedback.

7.   Create Visual Aids

Think about any visual aids , such as slides, you may want to use to illustrate your defense and prepare them in advance. Be sure to check that your university allows visuals or images and that they enhance, rather than overwhelm, your presentation.

8.   Stay Calm and Confident

It’s natural to feel nervous but try to stay calm and composed during your defense. Take deep breaths and remind yourself of the expertise you’ve gained through the experience of writing your dissertation.

Defend A Thesis: Prepare For Your Thesis Defense For PhD

When you’re nearing the end of your graduate program, a critical milestone looms: the thesis defense. This isn’t just a formality; it’s your chance to showcase the depth of your research and knowledge. 

In this post, we explore what is a thesis defense, the process, and how you can do well in it. 

What Is A Thesis Defense?

A thesis defense is a crucial component of completing a graduate degree, where a student presents their research findings to a panel of experts, typically comprising faculty members from their university.

This event marks the culmination of a student’s research efforts and is a formal requirement for obtaining a master’s or PhD degree.

A thesis defense is also quite similar to a dissertation defense. Both involves a student presenting their research to a panel of experts and answering in-depth questions.

The main difference typically lies in the level of study—thesis defenses are common in master’s programs, while dissertation defenses are associated with doctoral studies. Both assess the student’s research rigor and depth of knowledge.

A thesis defense is usually a nerve wrecking experience for many PhD students, but with the right knowledge and preparation, it is usually managable.

Why Must a PhD Student Defend Their Thesis / Dissertation?

There may be doctorate programs that does not require thesis defense, but PhDs generally need to do this. There are several reasons why PhD students must defend their thesis:

Demonstration of Expertise

A thesis defense compels you to consolidate your research into a coherent presentation, showcasing your depth of knowledge and critical thinking skills.

During this oral examination, you answer open-ended questions posed by a committee of faculty members. This is your chance to demonstrate that you are an expert in your field, having moved from a student to a scholar.

Mastery of Subject Matter

The defense process requires that you not only know your study’s details but also how your work fits into the broader field.

Committee members, including your advisor and other professors, will probe your understanding, asking you to justify your methodologies and conclusions.

This is akin to a rigorous job interview where your task is to convince them of your thesis’s merit.

Feedback Opportunity

This is a rare moment to receive direct, critical feedback from multiple seasoned academics. Their insights can profoundly shape the final version of your dissertation, refining your arguments and possibly influencing future research directions.

Engaging with their questions helps you think more deeply and respond to critiques that you might face when publishing your work.

Validation of Research Efforts

Defending your thesis validates your years of hard work. Successfully articulating your research process and findings in front of the defense committee is a significant accomplishment in itself.

It’s a formal acknowledgment by the academic community that your research contributes valuable knowledge and meets the rigorous standards required for a graduate degree.

Professional Preparation

The skills you hone while preparing for your defense are invaluable in any professional context, including:

• articulating complex ideas,
• responding to unexpected questions, and
• handling critique.

Whether in academic conferences, teaching scenarios, or even non-academic jobs, the ability to present and defend your ideas clearly and professionally sets you apart.

In the grand scheme, your thesis defense is more than just a formality. It’s a crucible that transforms years of research into a defended, deliberate statement of your academic capability.

It’s not just about answering questions; it’s about proving that your research stands up to scrutiny and contributes to your field.

What Happens In A Thesis Defense?

Thesis defense is a very long process. You start with months, sometimes years, of preparation, writing and completing your thesis.

You will defend your work before a committee usually made up of faculty members from your department, and possibly an external examiner. These are the experts in your field who will rigorously evaluate your research.

The defense itself is a formal yet dynamic process. It begins with you presenting your thesis, often through a detailed PowerPoint presentation. This presentation highlights:

• the main points of your research,
• your methodology, and
• your findings.

Think of it as a summary of your long journey—a chance to argue the significance and validity of your work.

After your presentation, the committee will ask questions. These aren’t just any questions; they are often complex, open-ended queries designed to test how well you understand your research and your ability to think critically under pressure.

You need to demonstrate not just knowledge, but a deep grasp of your topic and related theories.

An interesting twist is that you may be asked to leave the room after your presentation. During this time, the committee deliberates on your performance. They discuss whether you’ve met the high standards required for a PhD and whether your thesis contributes significantly to the field.

This can be a nail-biting time for many students, as the discussion behind closed doors determines the outcome of years of hard work.

If all goes well, they will call you in, and inform you that you have passed your thesis defense. At this point, you may hear yourself being addressed as a ‘Doctor’ for the first time. 

If theres hiccups, you pay still pass, but with corrections. This means you need to perform additional work on your thesis for it to be accepted. In worse cases, you thesis may require major corrections. Some examination panels may also require you to redo your thesis defense.

This is fortunately, not very common. This is because your supervisor would have ensured your work is up to par before submitting your application for thesis defense.

How To Prepare For A Thesis Defense?

Preparing for your thesis defense can be daunting. You’re about to present years of work to a committee that will scrutinize your research and knowledge. Here are ten tips to help you prepare for your thesis defense.

1. Understand the Format: Every university has its own rules for thesis defenses. Check with your advisor or the graduate office to understand exactly what’s expected of you. Whether it involves a public lecture or a closed session with your committee, knowing the format helps you prepare effectively.

2. Focus on the Core Ideas : Resist the temptation to include everything from your dissertation in your presentation. Highlight the most significant findings and methodologies. This approach helps you stay within time limits and keeps your audience engaged.

3. Anticipate Questions : Think about potential gaps in your research that faculty members might target. Prepare slides or notes that can help you answer these tough questions. This foresight can turn a difficult question into a demonstration of your thorough preparation.

4. Rehearse Extensively : Practicing your presentation multiple times is crucial. Try to simulate the defense environment as closely as possible, ideally in the actual room where you’ll present. This rehearsal will make you more comfortable and fluent during the actual defense.

5. Prepare Visually Clear Slides : Your slides should aid your presentation, not confuse the audience. Ensure they are clear, visually appealing, and free of clutter. Use diagrams, charts, and bullet points to effectively convey complex information.

6. Dress Professionally : First impressions matter. Dressing professionally respects the formality of the occasion and can also boost your confidence. A business suit is often the go to for most candidates, although some universities may be more relaxed on the dress code.

7. Create Backup Slides : Have additional slides prepared for deeper dives into specific topics. These are particularly useful if a committee member asks a detailed question about a particular point or method.

8. Know Your Committee : Research the interests and work of your committee members. This knowledge can help you anticipate the kinds of questions they might ask and prepare more targeted responses.

9. Stay Calm and Collected : Remember that defense is not just an examination but also an opportunity to showcase your work. If you don’t know an answer, it’s okay to admit this and suggest how you might find it out. This shows honesty and a willingness to learn.

10. View It as a Professional Dialogue : Approach your defense as a professional discussion rather than an interrogation. This mindset can change how you perceive the event, reducing stress and helping you engage more openly with your committee.

These strategies are about more than just surviving your defense; they’re about making the most of an opportunity to excel and impress

Prepare For Your Thesis Defense

Your thesis defense is not just a formality; it’s a bridge to your future career and a chance to shine. Prepare diligently, understanding that this is as much about demonstrating your grasp of the field as it is about honouring your own hard work.

With the right preparation, you’ll be able to defend your thesis with confidence and leave a lasting impression on your committee.

Timeline to defence

Early planning considerations.

Well before your defence date, there are several considerations to think about that can help make the end stages of your degree go smoothly and ensure your defence date and degree completion are not delayed:

• Being aware of formatting requirements will save you time on revisions later on – the last thing you want to be doing before submitting your thesis to UWSpace is updating page numbers or your table of contents! Consider using the Microsoft Word or LaTeX thesis template produced by Information Systems & Technology. 
• The Dissertation Boost Camp can help you develop effective writing practices and strategies for completing your thesis, while the three-part Rock Your Thesis workshop series will provide practical guidance for planning, writing, revising, and submitting your thesis project. You can also book an individual appointment to do backwards planning with an advisor. They can help you utilize the planning tools most effectively, while providing hands-on guidance and feedback.  
• If you are using third-party content, including your own previously published work in your thesis, or seeking intellectual property protection (for yourself or another involved party), there may be implications for your thesis or defence. Learn more about copyright for your thesis , and email [email protected] for help with copyright questions related to your thesis.
• Depending on your departmental or discipline’s norms, you may require approval from your entire committee, or just your supervisor. Ensure you talk with your supervisor and/or committee early on to confirm processes and timelines, so you’re not surprised later.
• Depending on your departmental or discipline’s norms, your supervisor may select an external examiner themselves, or they may seek your input. Talk to your supervisor early on about this process, as in some faculties the external examiner may need to be vetted and approved as early as the term before you wish to defend. Remember that there are conflict of interest guidelines around the appointment of the external examiner , and the PhD candidate should not be in communication with the external examiner prior to the defence.
• A PhD thesis must be on display for a minimum of 4 weeks prior to the defence date. To accommodate, you may need to submit your thesis as early as 6-8 weeks prior to your defence. Review your faculty specific backwards planning tool for the thesis submission deadline in your faculty and learn more about the display period in the PhD thesis examination regulations.
• After your successful thesis defence, you will likely have some required revisions to your thesis. It’s important to understand revision timelines , especially if you’re hoping to become “degree complete” before a tuition refund or convocation deadline. Find tuition refund and convocation deadlines in the important dates calendar .
• Following your thesis defence, there are several steps to be taken before your final, approved thesis is accepted in UWSpace. Ensure that you’re aware of these thesis submission steps and timelines in advance.

Backwards planning tools

Graduate Studies and Postdoctoral Affairs, in collaboration with the Faculties, have prepared faculty specific backwards planning tools to help PhD candidates map out the timelines related to their thesis defence and degree completion.

Defending a PhD thesis like a boss!- an in-depth Guide

A thesis defense is a two-way process of PhD evaluation, a session during which experts ask questions related to the PhD dissertation for awarding a PhD degree.  

Defending a PhD thesis or dissertation is the last station of the PhD. The process of a doctorate is different! Even though prospective candidates don’t need to appear in the written examination, the thesis defense is a must!

It’s a process occurring behind closed doors or openly (sometimes!), under the supervision of subject experts or all, to award someone a prestigious doctor of philosophy degree .

PhD- the Philosophia doctor is a path full of complications and problems. Starting from admission to writing a thesis or viva, a candidate has to achieve every milestone to move forward towards a PhD. 

Broadly, a good graduation or master’s score, completion of the entrance exam, course work, PhD thesis, publication in a peer-reviewed journal, PhD presentation and well-completed PhD research are criteria to appear in the PhD defense. 

If a candidate fails to achieve any of the requirements given above, he or she can’t go-ahead. The PhD is all about research, passion, knowledge on one side whilst depression, lack of confidence, loneliness, frustration on the other side, nonetheless, it is a fun journey. 

Defending a PhD thesis at terminal can relax a doctoral student, although should not be taken for granted. 

The present piece of content is all about defending your PhD thesis, what is it and how to appear. I will also give you some tips that help you to successfully complete it. 

What is a thesis defense? 

The thesis defense is the terminal process of discussing ‘research’ to award the PhD degree. It is also referred to as PhD viva too; however, it is more a discussion session than a viva. 

A prospective student has to appear in the thesis defense along with the PhD thesis, a presentation and all other PhD related documentation. A student also has to carry all the materials and proofs that can be used to convenience a supervisor or expert to award the doctorate. 

The entire process is verbal. Two external subject experts, a guide, and a university VC conducts the process, note that other students can also appear in the PhD defense process too as a guest. 

Universities usually conduct close viva sessions to avoid ‘personal bullying’ during the thesis defense. 

During the process, questions are based on the thesis content, topic and subject of the prospective student’s research. The objective of conducting the defense session is to check the knowledge of a student, research aptitude and how he or he had done their research. 

It is a kind of evaluation process in which experts ask questions and point out gaps in research presented by a student.

What is the process of thesis defense? 

The process of PhD thesis defense starts with the general introduction of experts followed by the presentation session. A candidate has to present their thesis in a PowerPoint presentation, keynotes or google slides. 10 to 20 minutes are alloted to present the work in 15 to 25 slides. 

Soon after, experts ask questions related to research. Several of them are, 

What is the purpose of the present research? 

Why is the present topic chosen? 

What is the study population and why only those are selecting 

What are the outcomes of the present work? 

Why are the results or outcomes important? 

What are the societal benefits of the present work? 

How or what the present research contributes to the present knowledge? 

These are the common questions asked to know the quality, quantity and strength of the research one has conducted. 

The process is of two types; close thesis defense viva and open thesis defense viva. 

In the close thesis defense viva, only a subject expert and a PhD supervisor conduct the entire process of the thesis defense, no one is allowed to interfere in it. A student can defend their thesis confidently, on the positive side, however, sometimes the integrity of the session doesn’t maintain due to lack of a monitoring body. 

During the open thesis defense, anyone can appear in the viva session including students of master’s and graduation. Also, anyone can ask questions related to the topic. 

Open thesis defense sometimes makes things harder for the prospective student. Which type of viva or defense system you have to face will depend on the university. The process and type of thesis defense vary from country to country and university to university.  

2 to 5 examiners or external evaluators are invited for a PhD thesis defense session by the university. The criteria to select examiners for the same are; they should be not from the university, they are experts in a related subject, they are working outside the university. 

University allows a PhD supervisor to the defense session but they can’t participate in the discussion. Examiner examines the thesis and will randomly ask queries to the presenter. 

Who conducts a thesis defense? 

The thesis defense of master’s, M Phil or PhD is held by the university under the vigilance of the supervisor for the student appearing in the degree. 

A PhD supervisor invites two or three other experts of the subject to conduct the session, university presentative or vice-chancellor closely monitors the entire process, if present.

How long a thesis defense occurs? 

Per student 10 to 20 minutes are allotted to defend the thesis, however, it may vary, depending on how long a verbal questioning session happens. If it is interesting, it may take up to 2 hours. 

Sometimes, experts wind things in 30 minutes too; that depends on how neatly you have written your thesis and how beautifully you have given your presentation. Still, a few questions are common and asked in every thesis defense. 

Usually 20 minutes to 2 hours it takes to complete the thesis defense. 

What happens after the completion of the thesis defense? 

Defending a thesis isn’t like giving a written exam, which means the results are not like ‘pass’ or ‘fail’. The results are like how excellently one has done their doctorate- research, thesis and presentation. 

There are three possibilities after completing the PhD viva or thesis defense.

• First, you have successfully completed it.
• Second, you have failed in defending the thesis- revision required. 
• Third, there are chances of improvement- minor revision required. 

When you present your thesis excellently, write the dissertation in a proper way and accurately- like a professional writer, proofread it correctly, complete all the objectives mentioned in the thesis, done research in a proper way, you probably come in the first case. 

A PhD degree will be awarded to you soon! 

If a thesis is not written in a good way, not all the objectives are completed, not published a paper, or fails to write a thesis completely or it is partially incomplete, you fail in defending the thesis, need revision.

In this case, you have to re-appear in the Ph.D. to complete the incomplete work. 

The third case is a bit different in which a student is advised to do some minor changes and improvements to make their own thesis much better. Usually, re-viva is not conducted in these cases. 

In the second case, in which a student fails to defend their thesis, re-viva and second round of thesis defense will be conducted after six months or a year. 

Note that awarding the thesis entirely depends on the external examiner.

Can anyone fail in the thesis defense? 

I can say yes! But not exactly because it is not an examination. A candidate has to appear again after sometimes to defend the thesis. Here are the cases in which we can say, a candidate failed thesis defense.

• Improper, incorrect or partial thesis. 
• Incomplete objectives. 
• Incomplete research work. 
• Lack of significant outcomes. 
• No publication 
• Fail to answer questions during the defense. 

Practically it is not considered as ‘fail’, re-viva or another round of thesis defense will be conducted. 

Tips to successfully defend the thesis for PhD: 

When you will be on your presentation, an examiner opens your thesis; thoughts of curiosity, nervousness, excitement and energy will flow around you, all at once. 

In these conditions, even if your preparation is excellent, a small mistake can ruin everything for you. 

You have to balance your positive as well as negative emotions at the same time. Here are some of the tips that definitely help you to defend your PhD thesis successfully. 

Fill yourself with positivity: 

You are very near to your goal, one step ahead of getting a degree- an utmost academic honor- the PhD. Surely, you need to balance everything, as I said, but to do so, you need to behave positively. 

Even if you know the gaps, problems, limitations and problems of your PhD thesis, yourself or your knowledge, you need to keep calm and behave like everything will be on your side. 

Only you know what is not perfect in your presentation or thesis, why to show it to others! Stay calm, focus, confident and positive like everything is perfect there. 

If you still feel so negative, imagine there are so many students in the world who have not even reached this level! You are here, on the last step of the PhD- feel proud of yourself.

Dress well, look well: 

To feel confident and positive, you have to look better. Wear a good, decent and formal dress, shave your beard or trim it, style your hair and polish your shoes. If you will look good, a positive and joyful atmosphere will be constructed in the room that will definitely help you. 

Don’t look tired, hopeless, restless, sleepless. 

Checklist all things: 

A couple of things are required during the PhD viva or thesis defense session. One is the presentation and the second is the thesis. In addition to this, don’t forget to take other documents related to your PhD like your plagiarism clearance certificate, your registration certificate and even your logbook. 

One can’t appear in the thesis defense session without a presentation and thesis. 

Other things are secondary in this case. 

Also read: How to Avoid Plagiarism in Your PhD Thesis?

Prepare a good presentation: 

Before preparing a PhD presentation, you need to know in which format the university allows to present the thesis. However, the globally accepted format is Microsoft Powerpoint. 

Prepare a good, decent and professional PhD presentation of 10 to 15 slides and save it in multiple formats. Include only necessary information, I know it is very difficult to summarize the 4000 to 5000-word essay in 10 slides. 

Also, don’t forget to include material, methods, theory, results and outcome of the research, those things are very essential. Make your presentation correct with your PhD supervisor before appearing in the thesis defense. 

Make a backup: 

What if your presentation will not run on the day of defending the thesis? What if you lost your hardcopy of the thesis? that is not good, right! 

 You are a PhD student , above all, out of the box thinking ability and good analytic thinking, how can you forget to make backups? 

Backup your presentation in a flash drive, cloud storage and email. Prepare presentations in multiple formats.

Make the back of the thesis soft copy as well and store it on different devices that are easily accessible in case of emergency. In addition to this, also prepare a rough and unbounded draft of the thesis hardcopy as a backup. 

Control yourself: 

Students who have done their PhD sincerely are confident about their work but it is very important to control yourself during the thesis defense. In any harsh condition don’t lose your calm, don’t be aggressive.

Even if you know that the expert is wrong- that is a rare case scenario, respect their opinion and behave accordingly. See it is obvious, no one knows more than you and your guide about your topic.

Try to explain things to the panel member, if it can’t work, leave it, respect their opinion and take it as suggestions. 

Read more: 10 PhD Programs You can choose to Study- A Comprehensive Guide .

Answer to the point: 

Sometimes it happens that you explain things more than the experts’ needs. There are drawbacks of explaining things elaborately, they can trap you! 

As I said, pay attention to the question asked by the expert and try to answer what they want, not more than that. Explain things if they don’t understand. 

Do this if you don’t have an answer: 

Experts’ duties are to find gaps and problems in your research so that they can find knowledge actually required. So it is obvious, they confuse you, and ask questions which you don’t know. 

 Don’t get nervous or panic, if you don’t know the answers. Take a deep breath and admit that you don’t have the answer or don’t have an idea about that. To support this situation, you can even make an assumption that this might happen or this will be the reason or give a probability.

See thesis defense is not like a viva, questions will be intellectual and will challenge your knowledge and thinking every time for sure. You have to show them your ability to think differently, not what to already know! 

Also read: 50 various PhD degree full forms .

Do this if something wrong happens! 

Days change, some are good, rest are bad. Things will be on your side someday, or not on other days. What you will do if something wrong happens whilst defending the thesis? 

Your presentation may not work, You lost your thesis, a big problem with the thesis- you didn’t know and problems in findings of results; these are some common problems I had seen in PhD viva. 

So you have to prepare for that, what to answer in those conditions. Anyone can make mistakes, simply apologize and request panel members that you will fix the problem soon. See, you have to act as per the situation, I can not tell you what you say in which conditions. 

For instance, if your presentation is not working or electricity is not there on the day of the presentation simply apologize for that, present it with the available utilities like chalk and blackboard.

The important thing is don’t panic, apologize first, and request to continue the presentation. For instance, if there is a major issue in the thesis, request the examiner that you will fix it, please allow you to continue the presentation. Try to complete your presentation, anyhow, who knows if they will impress. 

Be prepared for the most common questions: 

 The 10th tip is very useful and kind of a hack for you. There are several questions asked routinely during every thesis defense session. For instance,  what is the purpose of your research? How outcomes help society? Why have you chosen this topic? Why have you selected this technique for your work? What are the applications of your research? Like that. 

Be prepared for these questions, a few of them will be asked during the session. Then after the discussion will pick the heat, and your thinking ability will be tested.

Conclusion: 

Thesis or dissertation and PhD viva or thesis defense aren’t mandatory for all. Some professional degrees seek only internships for the award of PhD or doctorate. IN PhD in medicine or psychology, thesis or viva isn’t conducted, though the criteria are decided by the universities and hence vary greatly. 

Still, the thesis defense is a common practice performed to award PhD, M Phil or post-graduation degree.

The Last Big Hurdle: How to Prepare for a Successful PhD Defence

It’s the moment almost everyone who completes a PhD both dreads and looks ahead to for years—the defence. It signals a major achievement, but in people’s imaginations, it can seem like the stuff of nightmares… standing frozen in front of everyone, unable to answer a tricky question posed by a committee member and feeling like you must look incompetent. The format of a doctoral defence varies from field to field, but the worst fears of the candidates remain largely the same. Though most people know it probably won’t go so badly, the open-ended-ness can certainly be intimidating- you’re up there alone in front of a panel of experts who get to ask you whatever they’d like, and you may have to deliver your answers in front of an audience of your peers. There are few experiences in academic life more geared to be stressful for the person at the centre of them.

It doesn’t have to be that bad. I spent the weeks leading up to my PhD defence in a state of near panic, but I can honestly say that once it actually got underway, I sort of enjoyed it. You’re the star of the show and get to walk your peers through the finer points of your research. It can be a really invigorating experience. So let’s try to break this down into bite-sized chunks and look at strategies and tips for making your defence an event you might actually look back fondly on.

What the committee wants

Let’s start with what the committee is actually looking for. They want to see a firm grasp of the subject matter, an understanding of the implications of the work, and the ability to see weaknesses in the methodology and possible routes to take for future work. This means creating a presentation that gives a clear, logical overview of your topic, the question you’re addressing, what you did, your results and conclusions, and where the research can go from here. Remember, your jury members are not out to get you. The questions you receive from them will generally fall under one of three headings- those that test your subject knowledge, those that clarify a confusing point, and those that arise from genuine curiosity. If your presentation does a good job of conveying your knowledge of your topic, you can expect more questions from the second and third categories, allowing you to think of the defense more as a conversation amongst experts than a test from on high.

How to prepare

Practice is obviously very important here. Once you’ve put your talk together, find a trusted friend or mentor (ideally, several of them) who knows your field to go through it with you. They can both help you to pare down unnecessary parts and point out logical leaps you may not have noticed because you’re so close to the subject matter. You also want this to be a person who will ask you tough questions and try to spot holes in your reasoning, so choose your test audience carefully. It can be tempting to spend a lot of time obsessing over your slides, trying to make them perfect, but there’s a lot of studying you’ll need to do to be ready for more tangential questions, so don’t lose too much time this way.

Even though you have lived and breathed your thesis topic for years, it’s a good idea to give your thesis a complete re-read just to make sure you really know what’s in there. It may have been months since you finished writing it, and parts may have gotten a little fuzzy since then. Make sure you know why you used the methodology that you did, be able to justify any conclusions you’ve made, and if there are mistakes, admit them openly at the defence and be able to talk about what you should have done differently—the committee isn’t looking for perfection, they’re looking for clear thinking and thorough consideration of methodology.

This is also a good time to review important topics that are peripheral to your work; this will allow you to answer some of the questions designed to test the limits of your broader knowledge of your field. One of the best pieces of defence preparation advice I’ve ever heard is to find out what each of your committee members’ professional interests are, and do a bit of reading on those topics. There’s a very good chance that they’ll ask you something that’s related to their own work, because that’s familiar ground to them, and you may be able to anticipate these questions this way.

Finally, though it’s less and less of a problem as technology improves, you’ll want to make very sure ahead of time that all your presentation gear works and connects properly to the display equipment in the room where your defence will be. No one wants to be running around at the last moment looking for a dongle they didn’t think they needed, or have their laptop’s battery run out partway through the defence. Check that your slides look the same way on the projection screen as they do on your computer- not cut off or too dark. It also doesn’t hurt just to spend time in the room in which you’ll be presenting, to get a feel for the place and see where everything will be positioned.

Common questions and ideas to think about

• What makes your project original, and how does it answer a previously unanswered question? What have you contributed to the body of knowledge on this topic?
• Why was this question important to ask? Why do we care about what your findings reveal? (Hint: “Just for the sake of knowing” is not an acceptable answer here.)
• Did the focus of your project change over its course? If so, explain how and why.

Methodology

• Why did you choose your methodological approach (including your statistical analyses)? Why is it superior to or more appropriate than all other methodologies?
• Talk about the difficulties you experienced with your methodology and how you addressed them.
• What are the limitations of your study design/methodology?
• Explain how your data represent an appropriate source of measurement to address your question.
• Is the amount of data gathered sufficient to address your question? Why or why not?
• If you could do it again with unlimited time and funds, how would your methodology change?

Conclusions

• What would you say is the most important “take-away” message of your work?
• Does your work have wider implications for other disciplines in your field?
• How do your conclusions support or contradict the existing literature?
• Are there alternative ways your data could have been interpreted?
• Speculate about what broader implications your research could have, but which aren’t addressed by your data, or were outside the scope of your project.
• If you were to continue on with this area of research, what would you do next to further your results? Is there a closely related “spin-off” question that needs to be answered?
• Propose an experimental design to test this related question. What results might you expect to see?
• Where do you think this field of study is headed in the next five to ten years?

Tips, tricks, and stress management

• Practice the first few minutes of your talk until you can do it on ‘autopilot’; this will give you a bit of time to relax into your presentation, get your thoughts in order, and begin talking more confidently.
• If your defence is open to the public, ask a few supportive friends or colleagues to sit where you can easily make eye contact while you’re talking. Seeing a friendly, smiling face can be encouraging and help you to relax.
• Don’t forget to review the newest literature in the weeks leading up to your defence—one or more important papers may have been published in your field since you wrote your thesis, and you’ll want to know about them.
• Have a hard copy of your thesis on hand during the defence. It’s much faster to flip to a physical page when asked about a particular section of the text. If this really isn’t for you, be sure you have a quick way to move through pages on your computer.
• Eat and drink the same things you normally would on the day of your defence. Your stomach may be extra sensitive in response to the stress, and you don’t want to surprise it with anything new. And go easy on the caffeine… jittery-ness will not help you to manage your stress!
• Try to let your enthusiasm for your subject matter show; your audience will feel more positive about your talk if they can see that you really find the work fascinating.
• It’s fine to take a moment to think about your answer before responding. The silence isn’t as long or as deafening as you think it is. And if you don’t know, just admit you don’t know—it’s okay to not know everything.
• Dress well, but comfortably, and try to project confidence. If you can speak to your committee as a group of your peers, it will reflect well on your growth as a scientist in training- and demonstrate you are someone who deserves to be awarded their doctorate.
• Don’t forget to publicly thank your advisor, your committee, and any other key people involved with your project for their time commitment and investment in your career.
• When planning post-defence festivities, be aware that you may be more tired, both mentally and emotionally, than you expected. Don’t ask too much of yourself in the hours following the event.

A bit of encouragement

Above all, there are two things you need to remember while preparing for your defence. First, your advisor and committee would not have allowed you to proceed to this point if they didn’t think you were ready. They want to see you succeed and, altruism aside, it would reflect badly on them as well if you were to fail. Trust that they’ve made the right decision. Second, after years of delving into your little corner of the scientific world, no one knows your thesis topic better than you do—not even your committee. Marshall your facts and feel confident in knowing that on this topic, you’re the world expert.

How to Defend a Thesis: An Introduction to the PhD Viva

The prospect of defending your PhD work can be more than a little daunting. It represents the climax of many years of hard work, you’ll have to defend a thesis in front of experts in your field and the whole PhD viva process can seem cloaked in mystery.

Maybe you’ve seen a labmate go for their PhD viva to then emerge several hours later, relieved but perhaps slightly dazed. Often it’ll be the case that they’ll have forgotten the specifics by the time they’ve left the room. On top of that, horror stories of bad PhD viva experiences pass through many research groups which are enough to make even the most confident and positive PhD students shake in their boots.

Having had my own PhD viva earlier this year, in addition to discussing experiences with many other PhD graduates, I now want to help you through the process.

Before we begin, I want to offer some reassurance. For most people the PhD viva is not at all the horrible experience we occasionally hear about. Even so, it’s still useful to know what to expect. I’ve therefore put together a series to help others understand the PhD viva process and how to defend a thesis.

Defend a Thesis: Overview of the PhD Viva Series

This first post will be an introduction to the PhD viva process and how to defend a thesis. Upcoming posts will cover:

• Viva Preparation: Common PhD Viva Questions
• What is a PhD Viva Like? Sharing Graduates’ Experiences
• How to Choose Your Examiners

If there is anything specific you’d like covered, please let me know! I’ll be sure to include it. If you’d like to subscribe to get notified of upcoming posts as they’re released you can do so here:

How is a PhD Assessed?

Typically the main output expected at the end of your PhD project is a thesis. You’ve put years of work into your PhD and the thesis details your contributions to your chosen research field. But how is the thesis “marked”? Who will decide if what you’ve written is actually any good?

This is where the PhD viva comes in!

The PhD viva involves you discussing and defending your work with experts in your field. The experts act as examiners to determine whether or not the university should award you a PhD based on your thesis and viva performance. The thesis is the written report submitted for a PhD, and the viva is a means of quality control to ensure that only suitable candidates are awarded a PhD by the university.

Although part of the purpose of a PhD viva is to ensure that the work is of a high quality, just as importantly it’s to check that you were the one who carried it out and that you understand what you were doing!

The PhD viva is therefore essentially an exam during which you’ll have to defend a thesis.

Here is the official “mark scheme” for a PhD at Imperial:

I recommend looking at the presentation which this screenshot came from: sadly I only came across it after my own PhD viva whilst putting together this post!

Steps to Completing a PhD

• Submit your thesis for the examiners to read ahead of the viva.
• Have the viva , where you’ll defend a thesis and discuss your research. The examiners will decide from a list of possible outcomes as detailed later in this post.
• Make amendments to the thesis as necessary.
• Optional celebration.
• Have the thesis amendments approved by the examiners and/or your supervisor and confirmation sent to the university.
• Upload the final copy of your thesis to the university.
• Eagerly await notification that you’ve been awarded a PhD by the university!
• Celebrate, Dr!

All celebrations except for the one after making changes to your thesis are mandatory!

PhD Viva vs PhD Defence

The words viva and defence are sometimes used interchangeably, but often are used to reference the different ways that the a PhD is concluded around the world.

A PhD viva (technically a viva voce ) is a formal examination of a PhD. It’s typical in the UK (amongst other countries) and it is a closed-event between yourself and some examiners.

Across much of Europe it is common instead to have a PhD defence . This still involves expert questioning but can be more of a ceremony and may even be open to the public. You can read about Siddartha’s experience , who completed his PhD in the Netherlands.

I went through a PhD viva and that’ll be the focus of this series. Nevertheless, there is overlap and you may still have difficult questions in a PhD defence, so the content in this series should still be useful no matter where you’re based.

In both a PhD viva and a PhD defence you’ll be expected to defend a thesis which represents the culmination of your work during the PhD.

Who is Present During the PhD Viva?

In the UK it is typical for the PhD viva to include:

• One or more experts from your university ( internal examiner ).
• One or more experts in your field from another institution to your own ( external examiner ).
• And sometimes your supervisor, though in my experience this is quite rare unless you actively ask them to be there.

The main role of the internal examiner is to act as a moderator and ensure that the university’s protocols are upheld. They’ll usually still have some questions for you, but on top of that they’ll make sure that the external examiner(s) are reasonable. They will also take charge of documenting the viva.

Often the external examiner will be more specialised to your field than the internal examiner, so expect them to potentially ask more tricky and technical questions.

As mentioned in the previous section, for PhD defences in other countries the event may be less of an exam (viva) and more of a celebration of your work. These can be a lot more open, with access granted to your friends, family or anyone else who is interested in the topic. I quite like this idea, especially when the research has been publicly funded!

How the PhD Viva is Structured

The structure of the viva will vary but a typical format is shown below. The times in brackets are how long the sections for my own viva were, thankfully not all vivas are over five hours long!

• Introductions (2 minutes) – greeting the examiners and they’ll usually quickly give an overview for how they want the viva to go.
• Presentation (10 minutes) – Not all examiners will want you to give a presentation, it’s best to ask them in advance. I believe many examiners like asking for presentations: both to ease into the exam and also to see how you do at distilling years of work into a short presentation.
• Discussion (Over 5 hours, yes, really!) – the long and potentially scary bit.
• A short break (~10 minutes) . You’ll leave the room (or video call!) and the examiners will come to a decision for your PhD outcome.
• Decision and final comments (10 minutes) – where the examiners will tell you what the outcome is of the viva – we’ll cover this in more depth in the next section.

The discussion in the middle of course is the main guts of the PhD viva, and the potentially scary bit. This is where you’ll get questioned about your work and thesis. What you get asked could vary considerably depending on your thesis and examiners.

I’ll save an in-depth discussion of my own viva for another post. In short, I received very few questions relating to the work or any fundamental underlying science. There were practically no questions to quiz my knowledge.

Rather than checking my understanding of the work, the viva was much more of a discussion of how best to present the work in the thesis. We spent roughly an hour going page by page through each chapter. This included suggestions for improvements to figures, changes in terminology and the like.

Possible PhD Viva Outcomes

At the end of the viva the examiners will give you feedback. This will include feedback on your performance in the viva. But as long as they’re satisfied that you carried out the work and that you knew what you’re doing, the bulk of the feedback will in fact revolve around your PhD thesis.

Technically there are lots of potential outcomes, as detailed here:

In reality here are the four main possible outcomes from the viva:

• Pass with no amendments . The examiners didn’t want to make a single alteration to your thesis. Well done you just have to submit the finalised thesis to the university and you’ve finished your PhD! I know a few people who’ve had no revisions but it’s rare.
• Pass with minor amendments Minor amendments include things such as correcting typos, rewording sentences and small alterations to data analysis and presentation. This is by far the most common outcome.
• Referral for resubmission ( major amendments). More substantial changes to the thesis are required or further experimental work is required to fulfil the requirements of a PhD. The examiners will decide whether or not this means having another viva too.
• Fail . Unless there are glaring issues or you didn’t actually do any of the research in your thesis yourself, you should be relieved to hear that practically no one ever fails. If you have failed, it usually points to systematic issues revolving around your supervisor: you shouldn’t have been allowed to get to this point. Usually the examiners would recommend that you be awarded a lower degree, such as a masters in research (MRes).

Slightly up the page is a screenshot from my own examiners’ report. You’ll see that I, like most people, passed with minor amendments.

Making Changes to Your PhD Thesis

Shortly after the viva you should receive the examiner’s report which includes a list of revisions for you to make.

If you’ve got through the viva with a pass, you can breathe a sigh of relief because the hard work is over! In a separate post I’ll be covering how the process to make my own minor amendments went.

No matter the outcome, it is possible that you’d like to make your own changes to the thesis since it’ll have been many weeks (or months) since submitting the draft copy for your viva. On reflection there may be things you’re not happy with. You are welcome to make changes to the document yourself.

If you’re interested in reading more about how to make the corrections to your thesis, read the article dedicated to it here: Minor Corrections: How To Make Them and Succeed With Your PhD Thesis.

After you’ve made changes, the final stage in getting awarded the PhD is submitting your finalised version of the thesis to the university. Shortly afterwards you’ll get the long-awaited notification that you’ve got your PhD!

Should You Strive For No Amendments?

In my opinion it’s not worth the effort of trying to get no amendments.

I’d personally rather spend slightly less time up front, knowing that more than likely I would have to made some amendments. You can never put in enough work to ensure there will be nothing your examiners want changed!

You could spent hundreds of extra hours endlessly going through your thesis meticulously before submission but your examiners can always find something they want you to change. In comparison, my own minor amendments only took two days of work.

Sometimes you’ll see someone mention on their CV that they passed with no revisions but it doesn’t really have any bearing on your PhD. Unlike most other qualifications, there aren’t really grades for PhDs: you either have one or you don’t.

During an early PhD assessment my assessor made a poignant joke about medical degrees: “What do you call the person who graduates bottom of their class in medical school? A doctor!” And it’s essentially the same with PhDs!

• 10 Ways To Successfully Defend Your PhD

First, what does it take to give a successful PhD Defense? How can you prepare, keep the stress levels low, and make sure you have the highest chance of success?

I’ll just say that everyone’s PhD Defense is unique and is unpredictable. Your talk/presentation is only as good as you want it to be. And you cannot fully prepare for all the endless possibility of questions. If you wrote a 200 page thesis, your thesis commitee can pick apart an error bar on a graph on page 133. They can ask you what you meant by a word in a random sentence in any given paragraph. Keep in mind, this is all just apart of the PhD hazing process, and in a sense is just to humble you. At the end of the day, if you wrote a good quality thesis and are CONFIDENT, you should have no problem successfully defending and leaving that room with a sense of relief. Either way, I wanted to share my experience while it is still fresh in my mind

1) Do not underestimate how long it takes to prepare your slides/talk and make sure you give multiple practice talks

When I turned in my thesis two weeks ahead of time to my committee, I thought the hard part was over. Although a very important milestone, don’t let your guard down. If you already have most your slides ready to go, then you are lucky. I ended up getting data at the last minute and my story changed. I had to make many model slides from scratch.

If you want to give a GOOD thesis talk, you need to practice multiple times . And this means that you don’t cram it all in a couple of days right before your talk. I’m not talking about giving just one practice talk. You need to give multiple group practice talks. In between, you need to practice on your own.

You certainly don’t have to memorize every word of your thesis defense talk, but you should have it well-polished. There is no limit (or requirement) on how many practice talks you should give, but give as many talks as it takes until you feel like you are ready. If you are unsure of the quality of your talk (or being “ready”), tape record yourself or watch a video of yourself to see just how good it is. You might be surprised when you play it back to yourself.

You should also time your talk. I noticed that I tend to talk faster (by about 5 minutes) when giving the actual public talk vs. when I practice on my own. The length of the talk can depend on many departmental factors. My talk was ~45-50 minutes long which also leaves time for questions.

Either way, do not procrastinate on your slides and/or talk until days before. Make sure you use the full two weeks to perfect your slides, polish your talk (and be very concise about your words), and review material you are unsure about.

2) Listen to other thesis defense talks

The best way to mentally prepare for your thesis defense talk is to listen to other thesis defense talks. I actually went and got a few talks on DVD (the good ones that I remembered). If their research is on a similar topic as your own, this would be more ideal-but take what you can get. When you watch the talk, ask yourself what makes it good or bad? Were they enthusiastic and sincere? Did they keep the energy throughout the talk? Were there some rough areas of the talk? When nerves are running high, talks may not go as expected. You can battle this nervousness by showing up well-prepared. If you are, the thesis defense talk is just a formality.

If you cannot obtain any thesis defense talks on video, make sure that you go to actual public thesis defense talks. At least go to one so that you have a good idea of how to TIE the whole story together and give your audience the big picture. Keep in mind that you are giving a talk to a general audience . This means that use of jargon and highly technical terms will only put your audience to sleep. Make sure it is clear and understandable. Simplify it the best that you can and put it in the larger context of your research field. Use cartoons or model slides (if necessary) to give your audience the general, overall picture.

3) Have your friends, labmates, and others drill you with questions

What’s the best way to prepare for unforeseen questions? Have others that are familiar with your work drill you with questions. Chances are that even though these questions may not be the actual questions you will be asked either by the public and/or your thesis committee, it prepares you to think on your feet. It also builds your confidence . And the questions that your labmates or friends ask you may just be the same question you will get asked on your defense day.

4) Re-read over your entire thesis and write out your own list of questions

You may be sick of reading your entire thesis over and over by now, but you need to keep everything fresh in your mind. I actually read over my entire thesis multiple times during my final two weeks and came up with my own list of questions that I thought my committee would ask me. In addition, I also came up with a list of questions that I had of my own (questions that I was unsure of or that I thought were a weakness of mine). If you cannot come up with a list of good questions, then you are not trying hard enough.

Even though my committee didn’t ask me my exact list of questions, the process of  coming up with my own list of questions-then finding the answers to those questions (beyond my thesis)-actually helped me gained a deeper understanding of my project. And it was a confidence booster in disguise.

5) Don’t let distractions get to you

Completing your thesis is a huge milestone. Those last two weeks until defense day can be stressful. Whether you are doing job interviews, applying to other jobs, or you want to “jump the gun” and finally start your post-PhD life, don’t give into temptation. Keep your guard up until your actual defense day. This is key to giving a good talk. You need to go in with the mindset that you will kill your presentation and give a long lasting impression to your audience. I have actually heard that some people who gave great thesis defense talks were offered a position shortly after (i.e. a postdoc).

You are going to want to do all those little tasks that you have been putting off for so long because you have spent X amount of months writing your thesis in solitude and you had no time to do them. Your list could be very long. I can tell you that one of the things on my list was to keep publishing blog articles and keep my blog running. I simply did not have enough time. Prioritize and focus on your defense talk and nothing else . If you are looking for jobs during this time period, I will be writing about this in Part 3 of this series.

6) Get plenty of sleep, keep your diet in check, and take care of yourself

This might be the most difficult thing for anyone. I struggled with this the most while writing my thesis. Skipping meals, late nights, overloading your system with caffeine just to stay awake. You have to fight it the best that you can. A month before my defense talk, I hit the gym 3x a week (for the first time in months). Everyone handles the anxiety of their defense talk differently. I am someone who thinks about it constantly. So it becomes hard to focus on other things, like taking care of yourself.

Once your thesis is turned in to your committee members, during those final two weeks- sleep and a proper diet are KEY. The day of your defense, make sure you are well-rested (don’t stay up all night stressing about it) and eat well. Don’t sell yourself short. By taking care of yourself, you ensure that you have the highest probability for giving a great thesis defense talk and showing your committee members that you are confident about your project.

7) Keep your cool and relax

When your defense day comes, you have to remember that you have put in a lot of HARD WORK to get to this point. You know your topic better than anyone . Because of this, you have no reason to be stressed out.

When your committee pushes you and asks you questions, they again will push you to your limits. You will meet a point where you won’t know the answer. Also, a question could simply be a future direction/experiment that you simply haven’t tested yet. Remember that they are simply trying to test your knowledge and humble you. You don’t have to know all the answers. Therefore, when you are answering questions, keep your cool and relax. Answer the questions the best that you can and you should have no problem passing. And in all honesty, the prelim (or qualifying exam) was much harder than the actual defense…

8) Don’t focus on the after-party until you have actually reached the after-party

Who doesn’t want to spend their final two weeks planning the celebration? Although I did have an after-party, I did not go to great efforts to plan it like a wedding party. As I said in #5, prioritize and focus on your thesis defense talk and nothing else. Plan your after-party while you are on break from your practice talk/preparing for questions/working on slides but do not make it a number one priority. Once you have passed, then you can change your focus. The feeling is indescribable (see #10).

9) Have a good structure

A good thesis talk also has a good introduction before going on to the next idea or slide. It should flow in a logical manner and be smooth. That is why #1 is important, because many people don’t spend enough time in the creation of good powerpoint slides. Your slides and talk have to MATCH up , meaning you can’t have really good slides and a mediocre talk (or vice versa) if you want it to go well.

This is why practice is important, and if you spend enough time on BOTH the talk/slides you will give a very good talk. A lot of times while I was actually practicing my talk, I had to go back and change the order/wording of slides or how I introduced certain slides (the wording) so that the flow would be better.

Be formal in how you word things (i.e. say “our data show that”… vs. “you see here that”…). To give a good introduction, it might be wise to use slides that ask a question in between. This question slide (break) in-between your next idea allows for your general audience to CATCH UP and understand your logic . Why are you doing this experiment? If you just show a bunch of your published data with no introduction (and maybe a title that gives an interpretation/punchline), you will overwhelm and bore your audience.

Many scientists forget that although they are an expert on their topic, what seems easy and understandable to them-does not apply to others outside of their field .

Before you go to your next data slides introduce the idea (based on this data I wanted to ask this question). Then tell them WHY you performed this particular experiment (which is basically in the form of a question). Once your audience understands why, go on to the next slide and give them your interpretation. In other words, don’t just jump to the interpretation . This will keep your audience’s attention and make sure that your thesis defense talk gets a lot of positive feedback and leaves a good impression on your committee members (it really does show).

10) Visualize yourself giving your defense each day and think about how good it will feel when it’s over

This one is pretty self explanatory. I will say that when it is all said and done, it feels like a huge burden has been lifted off your shoulders. It is emotional and you finally feel that all that hard work and time that you put in over the years-was all worth it in the end. Good luck to all those who are preparing for their defense talk in the future! Think about what it will be like to get up in front of a large audience and show everyone how you moved a field forward. This is YOUR moment to show everyone you are an expert in your field. The more you keep this mentality, the better your talk will be. Keep your cool and relax (#7) and everything will be fine.

Best of luck to all!

Trapped in dissertation revisions?

Preparing for your dissertation defense, published by steve tippins on april 4, 2019 april 4, 2019.

Last Updated on: 30th August 2022, 04:43 am

Preparing for your dissertation defense is one of the most important things you’ll do as a doctoral candidate. Now that you’ve completed your dissertation, it’s up to you to present the results to your committee.

However, the results aren’t just about your study. Your committee wants to see what you learned through the process and whether you are ready to take on the responsibility of being a scholar.

What is a Dissertation Defense?

When you finish your dissertation and your committee has said you are ready to move forward, there is a formal meeting–your dissertation defense–where you have the opportunity to explain what you did and what you found.

Your committee then has the opportunity to ask questions related to your work, the implications of what you found, and your future. It is a chance for you to stand before your peers and be welcomed into the academy. Defending your dissertation is one of the great rites of passage into the world of academia.

How to Prepare for Your Dissertation Defense

Rather than write a quick list of dissertation defense tips, I thought I’d create a comprehensive guide to defending your dissertation. After chairing and sitting on countless dissertation committees, these are the steps I recommend you take.

Cultivate The Right Attitude

Perhaps the most important thing to have as you prepare to defend your dissertation is a revised view of your academic self. You’ve spent years gaining knowledge on your chosen subject, and now is your time to shine. While it’s natural to be nervous — after all, you’re jumping the highest hurdle in academia — keep in mind that this is your moment to shine and that you are now an expert on the topic.

One way to look at the dissertation defense is as a rite of passage. You are being tested, and just as with any rite of passage, the more rigorous the test, the prouder you will be of making it through.

During the process of your defense, keep this in mind: your committee tests you not only to ensure your worthiness but also to enable you to see just how much you know; to step into your new role as “expert.”

Prepare For Your Committee’s Questions

With this attitude in mind, you will want to prepare to demonstrate your expertise. That means anticipating questions the committee may have about your research.

If your dissertation asserts the likelihood of a recession in the presence of particular economic indicators, your committee will want to know what socio-political conditions are linked to these indicators. If you found that high achieving students are more likely to have had parents who volunteered in their schools, your committee members will likely ask you to speculate about how to increase parent involvement in schools.

In other words, you’ll need to be able to participate in discourse beyond your results — questions that speak to the relevance and implications of your research.

This kind of preparation goes beyond creating a PowerPoint of your findings (though that is necessary too); it’s part of your stepping into your expert role.

One thing I always tell my students is “Be able to explain your topic to your grandparents,” because to elucidate someone who knows nothing about the topic (no offense to the grandparents!) you must know it inside and out.

Of course, you’ll also want to know your topic well enough to discuss the topic with the top researchers in the field, but at this stage, you’ll have read enough of their work that you’ll feel you know them personally. It’s usually more difficult for academics to simplify than to complicate.

To ready yourself for potential questions, give your abstract to a few friends outside your academic program and have them ask you questions about your study. The advantage is their “outsider” perspective; you’ll have fun answering their questions and will likely have to make a few new neuronal connections to do so. Practicing like this will also help you relax during the actual defense.

Here are some questions you may be asked during your dissertation defense :

• “What are the strengths and weaknesses of your study?”
• “What was the most surprising thing you found?”
• “What will you do next with your results?”
• “If you could do this over, what would you do differently?”

Organize Your Presentation

Keep in mind that your presentation to your committee can double as your presentation to the faculty at any university to which you apply; your preparation will serve a dual purpose. You’ll need, therefore:

• a concise overview of the literature in which your study is grounded,
• a clear description of your study’s purpose, methodology, and findings,
• and a discussion of the implications of these findings.

Naturally, you will need to consult your department’s and college’s specific requirements, but every dissertation committee (and faculty search committee) will want to fully understand these basic elements of your work.

I have provided a list of questions to help prepare your dissertation defense. If you have time restrictions I would put more emphasis upon your results and the implications of your work. Think of organizing your slides according to these questions:

1. Why did I choose to study this? Don’t be afraid to reveal something personal about your motivation, as long as you can do so with poise and dignity. Your committee members will appreciate this humanizing element but keep it brief!

2. What have other people interested in this topic found? If your study is the next clue in the hunt for answers about this topic, what were the clues that led you here? What paths have past researchers gone down — both fruitful and not? What solid theoretical foundation stands under your study?

This portion of your presentation is the easiest to overdo. You will likely need to edit it again and again to ensure it is both concise and comprehensive. Stick to the major themes in your presentation but be prepared to answer questions about less dominant streams of research.

3. How did my research question evolve? Answering this question links your research to what has already been established, placing your study in the stream of knowledge. Keep it brief but don’t skip this step, as it is key to showing you as an academic, rather than a student.

4. How did I organize my study? This is a description of the basics of your study and the “whys” of these choices. You can expand a bit here, as the decisions you made at this stage demonstrate your ability to think critically about approaching a research question. Why did you choose your particular methodology? What was the benefit of this design over another option you might have chosen?

5. What did I find? You can begin this section with what you expected to find and why, then explain what you actually found. Keep this section simple and factual.

6. What do the findings mean in relation to the question? Whether or not your findings matched your expectations, they tell you and your colleagues something important about the topic. What is it? Can we speculate that this is a promising area of research, or is this a path we might think of as a dead end? What, exactly, does this study tell us?

7. What’s next for me and for the research? You’ll want to give your committee (and any faculty search committee) a preview of your prospective academic career. What new questions has your study sparked for you? What would you hope other researchers would look at next? How do you intend to fit into the academic conversation on this topic?

Depending on your committee and requirements, you may want to include potential grants you will consider applying for to fund your next study. (This inclusion becomes more important when applying for academic positions.)

Prepare Yourself Mentally

Going back to attitude, remind yourself that a dissertation defense is your opportunity to step into your new role. This is your domain now. Breathe deeply and feel the pride that comes with a job well done. Know that you belong in this realm and the dissertation defense is your chance to prove it. Be humble, too; after all, you stand on the shoulders of giants.

Getting enough rest the night before, drinking water and bringing some with you to drink when your mouth gets dry, and being wise about what you consume prior to the defense (maybe go easy on the carbs and caffeine) are all obvious but frequently overlooked pointers. Your committee members want to know you can handle the pressure and take care of yourself under duress .

You might want to give yourself a few minutes of silence and rest before heading in to defend. Take those moments to recognize whatever you’re feeling, then humbly begin your academic career by presenting your most important work to date. And then get ready to roll up your sleeves for the next one. Congratulations, Doctor!

The 3 habits that saved my phd, how to design figures for your phd thesis.

What’s the best way to prepare for your PhD thesis defence? The tips below will help you in the final few weeks before the exam, but the real preparation begins as soon as you start your PhD . Talking to people and discussing your work regularly over a long period of time is the best preparation, so don’t let your thesis defence be the first time you get feedback on your work!

Know the format of your PhD thesis defence

The format of a PhD thesis defence varies from country to country. Having studied in the UK, my viva-voce defence was essentially an interview with one internal and one external examiner. In other countries, it’s common to have public examinations with a whole panel of examiners and an audience of colleagues, family and friends. The first and most obvious tip, then, is to make sure you know what the format of your exam will be; whether you will have to prepare a presentation and so on.

Prepare and practice your presentation

If you have to give a presentation, check any time restrictions so you can prepare accordingly. You don’t want to show up with 100 slides for a 15-minute presentation, nor do you want to show up with 3 slides for a 1-hour presentation.

The most important thing to do for any presentation is to practice so that;

• You know the material inside out
• You know how long it takes
• You can refine the presentation

You can practice on your own or with an audience, and you should do both if possible. Practicing on your own and speaking out loud to an empty room may feel silly, but overcoming that discomfort is good preparation for the discomfort of facing an actual audience. Practicing with an audience of peers is then a good way of getting feedback and finding out what questions people ask.

A common fear is being asked a question you can’t answer. It’s tempting to try to read a ton of literature to prepare for this, but since it’s very difficult to predict what the examiners will ask and it’s impossible to read everything, this approach isn’t always effective or reassuring (it might just make you realise how much you don’t know).

You aren’t expected to know everything. Sometimes, an examiner will ask a question they don’t know the answer to, either out of interest (since you are the expert in your research) or because they want to see how you think. While it is OK, sometimes, to just say “I don’t know”, you could also say something like,

‍ “I don’t know, but I would think that […] because of x and y , but you would need to do […] in order to find out” .

This shows that you have the ability to think as an academic.

Core content

Of course, there is some core content which you will be expected to know well, but this is set by you, not the examiner. To a large extent, the content of the examination is determined by the content in your thesis.

When you choose what to cover in your thesis you are choosing your battleground for the thesis defence. The best strategy, then, is to stick to the material you know best in your writing!

Dealing with nerves in your thesis defence

You will be nervous before your examination. You will almost certainly get an adrenaline rush, which can set your heart racing, give you sweaty palms, make your stomach churn and make you want to go to the toilet 10 times in 20 minutes. This is normal!

The worst part is waiting to start because there isn’t much you can do to use up your nervous energy. But once the defence starts, you can do some things to keep it under control.

One symptom of nerves is to talk really fast and to try to show how much you know and speak in this kind of long stream of consciousness that diverges away from the question until you forget what the actual question was but then you don’t know how to get back to the point and so you just keep talking and that makes you more nervous and how are you going to get off this train of thought…

Try to slow down and give yourself time to breathe. Try to remember the question* and come back to the point. Once you have answered, stop talking!

*If you forget the question, it’s OK to say, “sorry, I got lost in my train of though there, what was the question, again?”

The examiners expect you to be nervous

Remember that the examiners expect you to be nervous, and they will help you through if necessary. It’s OK to ask them to repeat or clarify a question, to pause to think, or to take a sip of water if you need to!

Ultimately…

Success or failure is determined mainly by the content of your thesis. If your research is good, and you actually did the work, it’s unlikely that a nervous performance in your defence will lead to failure. Generally speaking, once your thesis is submitted, there isn’t much you can do to affect the outcome (positively or negatively). Read through your thesis, read up on one or two key points if necessary, practice your presentation, and trust that whatever happens you will be OK.

What title do you hold after you've defended but before you graduate?

Two friends successfully defended their dissertations yesterday, and many people have congratulated them, calling them Doctor so-and-so. I explained to my wife that they actually don't have that title until the graduation ceremony, that it's similar to a President-elect, who isn't called the President until they are sworn in. So, what title does a doctoral candidate take after they've defended but before they graduate?

There isn't a formal, universally accepted title here. The general standard has been to call them "Doctor" since everything else is in principle a formality.

The only other note that I'd make is that it's not commencement that makes the student in question a doctor, but rather conferral of the degree by the university. Some universities may confer degrees multiple times per year, but only have one commencement ceremony.

So, I would not include "Ph.D." next to my name, but in the education of my CV, I'd write "Ph.D. (to be conferred Month Year )," as that is entirely accurate representation of the state of affairs.

Formally, they don't take a title before the university awards it, and the awarding is usually done by handing out a certificate stating the title (independent of whether that involves a ceremony or not).

In informal situations, it's nice to address them with the title because they are usually happy and proud of their accomplishment, and what remains to be done before they actually get the title is more or less a mere formality. But you shouldn't put any doctoral title on name tags, staff directories, or anything formal like that before they actually get the document.

• 6 I suppose this is similar to me calling myself a "dad" even though my daughter won't be born for another two months? –  Jonathan E. Landrum Commented Oct 10, 2013 at 19:00
• 4 @JonathanLandrum Yes, that's a nice comparison. Everybody will be fine with that, but you can't put it down in any official documents yet. –  silvado Commented Oct 11, 2013 at 6:32

In most countries "Dr" is an honorific (in Germany I believe it is a legal title and part of your name) that is typically used when referring to individuals that hold certain types of degrees (most doctorates but not all, for example holders of the JD degree are not typically called doctor, and some non doctorate degrees, for example a BMedSci in the UK). As it is an honorific I think it is perfectly reasonable to bestow that honor to someone during a party to celebrate a doctoral defence. Similarly when seeing someone the first time after the defence using doctor is a nice why of honoring them. In some countries one can pass the defence and still need to make substantial revisions. I would use the honorific as long as the person passed.

In non-formal situations I would avoid it, but then again I avoid using the honorific even for people with doctorates. In formal situations where honorifics are being used I would definitely avoid it. I think it would set a bad tone to go to a job talk an allow yourself to be introduced as doctor. In that situation I would deflect the honorific and say "not yet"

In the (British) English Language the correct name for someone who has qualified to graduate but has not yet done so is a graduand .

One could formally say you are a doctoral graduand, but only other academics would understand.

Also, at the ceremonies in British Universities, the point at which you hold the title is when the Chancellor (or similar awarding officer) intones the word "I award upon those students who have qualified the degrees listed in the official record.. etc". Until those words have been said, whatever handshaking and parading has happened, you do not have a degree!

In Germany, it is "Doctor Des." standing for Doktor Designiert (designated doctor)

Defending your thesis or dissertation.

Certain special exams are required to earn an advanced degree in the research-based programs at Cornell. Often, these exams need to be taken with consideration of anticipated completion dates.  Enrollment in future semesters after the date a student passes their M or B exam is not permitted. See Taking Exams for more information.

All exam forms are available on our Forms  page.

Exams Required for M.A. and M.S. Degree Defense

If you are enrolled in an M.A. or M.S. degree program, you must pass the final examination for the master’s degree. You can take this after all degree requirements have been fulfilled, but no earlier than one month before completing the minimum number of enrolled semesters.

To pass the exam unconditionally and receive a degree, all regular, proxy, and field-appointed members of the examining committee must assent that the exam was passed unconditionally. If you are enrolled in an M.S./Ph.D. degree program where the M.A. or M.S. degree is a prerequisite for your Ph.D., you may petition your special committee to approve combining the final examination for the master’s degree with the examination for the admission to candidacy.

Exam forms required for the master’s degree include “Schedule Master’s Examination” and “Master’s Exam Results Form and Instructions.”

Exams Required for Ph.D. Degree Defense

The B exam is an oral defense of your thesis or dissertation. This exam can be taken after completing all degree requirements, but not earlier than one month before completing the minimum number of enrolled semesters. At least two semesters of successful registration must be completed between the passing of the A exam and the scheduling of the B exam.

Exam forms required for the Ph.D. degree include “Schedule A Examination and Research Compliance Form,” “Schedule B Examination,” “A Exam Results Form,” and “B Exam Results Form.”

The qualifying exam, or Q exam, is required in some fields for Ph.D. applicants. This exam helps the special committee determine your ability to pursue doctoral studies, continue in a program, and tailor an appropriate program of study.

Hints for PhD Defenses

At Columbia, PhD defenses are generally not public, although CS usually allows a student audience. Defenses consist of four parts: first, the candidate introduces themselves, then presents a summary of their work, interrupted and followed by questions from the committee. Finally, the committee meets in private to discuss the presentation and dissertation.

While most of the committee will have read most of your thesis, you cannot assume that everyone has read every chapter.

The committee needs to be able to assess impact and depth. Usually, the committee has some idea of this before the defense, but whatever the student can say to make this assessment easier, perhaps just through emphasis, is likely to make the defense go much more smoothly.

Generally, the whole defense will not take more than two hours, but should take considerably less time. Part of the challenge of a defense is to convince the committee that you can summarize the important points of your work in a very limited time.

• What is the problem you are studying?
• Why is it important ?
• What results have you achieved?
• Some committee members will want to know if the works has been published and where and how it was received. For example, if you have written software, indicate where it is being used, either for follow-on work or in some production or test environment.
• Have a list of your thesis-related publications as a slide. Indicate any awards that a paper may have received. For most people, it's easier to list some honor than "brag" about it in person.
• If you have presented your work in a conference or at job talks, be sure to anticipate and address the most common questions asked there.
• The committee should be handed a copy of your slides.
• Be prepared to briefly summarize your background (undergraduate degree, how long at the university, etc.)
• No more than 30 slides, plus "back up" slides with additional material in case of questions. The most effective way of making your committee members mad is to come unprepared with a stack of 80 slides and then madly skip through them.
• Number your slides, particularly if one of your committee members is linked in via speakerphone. Consider using some kind of remote presentation software.
• List your contributions early.
• When presenting your contributions, be sure to use "I" and not "we" so that the committee will know what aspects of the work where yours, and which were group projects.
• Keep discussions of related work very brief, but be prepared to answer questions of the "how does this differ from so-and-so's work" succinctly.
• You will not be asked to prove results again.
• Be prepared to back up any comparative statement with facts, in particular statements like "works better", "faster", "scalable" or "optimal". If you are presenting a protocol, how do you know that it works correctly?
• If you have multiple parts in your dissertation, consult with the committee ahead of time as to whether it makes sense to omit some of them for the presentation.

Hints for Dissertations

• It is better to focus deeply on a single area then to work on several topics, each of which is pursued to a moderate depth.
• Systems work must be coupled with implementation and some kind of numerical comparitive analysis to demonstrate the improvements from existing or alternate approaches.
• Your thesis needs a one page executive summary that a layperson should be able to understand. Test: give it to a relative of yours that does not have an engineering degree...

Miscellaneous Hints

• You are likely only to defend a PhD thesis only once; your defense is a special occasion, so consider dressing appropriately, at least business casual, but a suit is not inappropriate.
• It is customary to provide refreshments for the audience, such as coffee, bagels, cookies and fruit, depending on the time of day.

The Role of PhD Committee Members

• Committee members (should) read the draft thesis (and provide feedback). Obviously, students appreciate an in-depth reading, but it is common for committee members to focus on chapters closest to their expertise. Reading depths varies - some provide line edits, others just suggest larger issues that should be addressed ("Your related work section in Chapter 10 is a bit sparse and ends in 2005."). While this is probably not the place to suggest "do another year of research", filling in gaps is ok and I'd rather postpone a defense by a month if needed. Before the committee gets the thesis, I've done a first or sometimes second reading, but the whole point of the committee is to keep the advisor honest (and complement his or her knowledge or taste).
• Committee members attend the PhD defense, usually in person. Typically, this lasts about 90 minutes. Take notes on any editorial improvements (e.g., "make clear that the throughput graph is measured in gallons/minute"). Vote on the outcome and sign the form.
• If the student is given a set of changes to implement, the advisor asks students to detail on how they implemented the changes, similar to how an author may respond to reviewer comments for a journal. The committee informally signs off, or not, on these changes. There is no need to re-read the thesis.

Checklist for Dissertation

• Spell check;
• Check for missing chapter or figure references;
• Section, Chapter, Figure are capitalized;
• All references converted from [1][2][3] to [1,2,3];
• Consistent capitalization in captions;
• Verify expansion of all abbreviations at first instance;
• Avoid "tremendous", "huge" and other similar adjectives;
• End to end -> end-to-end;
• Check references for capitalization of abbreviations and missing data such as page numbers.

Defending your doctoral thesis: the PhD viva

Format for defending a doctoral thesis.

Every institution will have specific regulations for the thesis defence. In some countries or institutions, the convention is for thesis defences to be public events where you will give a lecture explaining your research, followed by a discussion with a panel of examiners (opponents). Both your examiners and the audience are able to ask questions.

In other countries, including the UK, the oral examination is usually conducted behind closed doors by at least two examiners, usually with at least one being from another institution (external examiner) and an expert in your topic of research. In the UK the supervisor does not participate in the viva, but may be allowed to observe. Sometimes someone from your own institution is appointed as an independent chair. Although it is now becoming more common for the candidate to have an opportunity to give a public lecture in UK institutions, this does not form part of the examination and may or may not be attended by the examiners.

Viva preparation

Take the preparation for your viva seriously and devote a substantial amount of time to it. The viva preparation checklist may be useful to help you prepare.

Your institution may offer courses on viva preparation and there may be opportunities to organise a practice viva. Take advantage of these opportunities: they can be extremely valuable experiences.

Things you may wish to take with you

• your thesis – mildly annotated if you wish
• a list of questions that you might be asked and your planned responses
• any questions that you want to ask your examiners
• additional notes which you have made during your revision
• list of minor corrections that you have come across during your revision.

During the viva

Your study will have strengths and weaknesses: it is essential that you are prepared to discuss both. You could think of any weaknesses as an opportunity to demonstrate your skill at critical appraisal. Examiners will seek to find and discuss weaknesses in all theses. Do not interpret criticism as indication of a possible negative outcome.

Examiners have different personalities, styles and levels of experience. Sometimes a candidate may feel that a challenge is made in a confrontational way. Experienced, effective examiners will not be inappropriately confrontational, but some will. Do not take offence. A relaxed, thoughtful, and non-confrontational response from you will help re-balance the discussion. Having an independent chair can help maintain a constructive environment.

Useful tips for during your viva:

• Ask for clarification of ambiguous questions or ask for the question to be repeated if necessary
• Take time to think before answering
• Be prepared to ask questions and enter into a dialogue with your examiners
• Be prepared to discuss your research in context of other work done in your field
• Be ready to admit if you don't know the answer to a question
• Be prepared to express opinions of your own

You are not expected to have perfect recall of your thesis and everything that you have read and done. If you get flustered, or need to refer to notes your examiners will understand. They have been in your situation themselves!

After your viva

There are several possible outcomes   of a thesis defence. Most commonly, your examiners will recommend to your institution that you are awarded your degree subject to minor corrections, although in some instances they might ask for more substantial work.

How to Defend Your Dissertation, Virtually

by Nitasha Mathayas, PhD / Apr 9, 2020

Tips on preparing, presenting, and celebrating from a new PhD.

On March 24, one day after in-person meetings and instruction at the university were halted and moved online due to the coronavirus pandemic, Nitasha Mathayas earned a new title: PhD. She delivered her dissertation defense—on students’ sensemaking using gesture-augmented simulations—via Zoom to her committee of Curriculum & Instruction faculty, her family, and friends. Over the next several weeks, many doctoral students will face the same situation. Here, Nitasha shares her experience and advice for holding a successful virtual dissertation defense.

Prepare Well in Advance

• Online meeting setup and structure: Several days before your defense is scheduled, talk to your dissertation committee chair and decide your conferencing platform and how to structure the meeting. One of my committee members, Dr. Stina Krist, hosted the Zoom video conference call and made me a co-host. She also managed the breakout session for the private discussion.
• Practice, practice, and practice some more on Zoom! (Or whatever video conferencing platform you choose to use.) Don’t just practice your talk like you normally would in person. Try giving the talk a few times to make sure you test everything out. I practiced my talk on Zoom three times with my colleagues and their feedback helped me adjust my pacing and presentation. Shout out to my Education peers for coming online multiple times on late evenings for me. You know who you are!
• Make adjustments: I like to point when presenting in person. But I could not do that remotely, so instead I added subtle animations and bolded things on my slides. While there is a laser pointer option with PowerPoint, it is better that the slides themselves highlight things you need to emphasize.
• Strong internet connection: While practicing, I figured out my home internet was not good enough to run the video call and my presentation, so I went to campus (was the only one there, social distancing was practiced), used an ethernet cable, set up a lamp, and ensured my environment looked professional.
• Professionalism matters: On that note, do everything you can to look professional. Dress formally, use a good webcam that is centered on your face (no weird angles). Use good lighting (add more lamps if needed) and have a clean background (no bright windows, distracting artwork, no pets in the background).
• Last call: Touch base with your dissertation committee a few days ahead of your scheduled defense to see if they have specific requests. For instance, one of my committee members asked me for my slides ahead of time.

Check—and Double-check—your Tech

• Connectivity: Before the defense begins, see if your committee members can hop onto the call 10 minutes early to check for issues on both ends.
• Two screens recommended: In terms of technical set up, I used my laptop and a second monitor. I presented my slides on my laptop and transferred Zoom’s control bar and attendee video to the second screen. This way there was nothing in front of my slides while I used them.
• Single screen works, too: If you use a single screen, you may have to minimize your speaker view to see your slides. If not, you might have to leave some empty space on your slides so you can put the attendee video there. A few people could not see text on my slides as their video panel obscured it.
• Test screen sharing options : Zoom has multiple options and things may get confusing if you use PowerPoint's automatic presenter mode. I set mine to use the primary screen only. I did not have access to slide notes, but I did not need them as I had practiced it well enough.
• Backup hardware: Keep a backup device (or two) ready to go in case you have technical issues. I had a backup laptop with me that I thankfully did not have to use. Yet later that evening, my dock gave out and my second screen went green. I really lucked out there. Phew!
• Record yourself: You can watch video of practice sessions to critique yourself, and you will also want to remember to record your actual defense.

Present, then Celebrate!

• Slides: I shared my final presentation file with my committee a few hours before my defense by uploading it to Box. This way they could access the slides at any speed they wanted, and I got to correct some typos without emailing them multiple versions. The upload file was the final version though, it was not a draft.
• View your committee: Ask other attendees to log off and log onto the call again after all dissertation committee members have joined, so that the committee appears on top of the speaker view.
• Explain the process: My chair described how we would structure the conversation. My presentation was about 30 minutes. He requested that my committee ask me clarification questions during the talk but to hold substantive questions for later.
• Questions: There was time for audience questions at the end from non-committee attendees. Audience members were asked to turn their video off during the talk but to turn it back on while they asked me questions. This really helped keep the committee’s videos up on top and I could see them when I needed to.
• Main room and breakout room: The main room was used for the public portion of the defense and was recorded, and then committee members moved to a breakout room that was not recorded. My family and friends waited with me in the main room while my committee discussed.
• Audience: I am glad I invited my friends to attend my oral defense. I was nervous and having them there made me much more confident when I talked. And they cheered with me when my advisor informed me that I had passed!
• Positive takeaways: There were some unexpected perks of my online defense. My friends and family from India were in attendance, which would not have happened if the talk was on campus. This way they were given the same experience as everyone else. Also, the Zoom session was recorded (a personal choice that everyone agreed to but is optional) so I now have a video of one of the most important days of my life to look back upon.
• Celebrate! Finally, plan to celebrate yourself. You did it! You made it! You deserve it! This is an important milestone, and it is unfortunate that you cannot celebrate in person. I set up a second Zoom party between 6-8 p.m. that evening and invited friends, committee, and family. We all toasted in our respective homes and people hopped on and off the call during that time. I was able to feel thankful and connected for a while. My friends and colleagues have given me so much and I was glad I could cherish that moment.

P.S. I also bought myself a Ph.Diva shirt. It’s not coming off for a few days. No one can smell it but me… phew for social distancing right now! Good luck fellow colleagues. You will all be great!

Was your Social Security number leaked to the dark web? Here's what to do first

You've likely never heard of  National Public Data , the company that makes its money by collecting and selling access to your personal data to credit card companies, employers, and private investigators. It now appears that the  hacker group USDoD snatched about 2.9 billion of its records . Odds are that your records -- including, possibly, your Social Security number (SSN) -- are in those databases. 

USDoD wanted to sell this data for the low price of $3.5 million. Ironically, before USDoD could profit from the theft, another threat actor, Fenice, swiped the data and released it on the dark web.

Also: The best VPN services: Expert tested and reviewed

How bad is it really? According to the security organization Vx-Underground , the stolen data includes 

• Address history (three decades' worth)
• Social Security number

Vx-Underground also found that "the database does not contain information from individuals who use data opt-out services."  These are sites or services that allow you to say no to a company or group that wishes to keep your records. 

That's good to know, but for many of you, it's probably a little late. 

The leaked data, totaling 277GB, can be used for identity theft and fraud. Although the breach does not necessarily affect 2.7 billion unique individuals (due to multiple records per person), it still poses a significant risk. The information can be used to open fraudulent accounts, apply for loans, or even commit tax fraud.

What to do first 

First, check to see whether your data is actually out there. The easiest place to start is with the Have I Been Pwned website. This should be your first resource to find out which breaches you and your data have been involved in and how extensively your data has been leaked. To use Have I Been Pwned, all you need to do is give the site your email address, and in less than a minute, you'll get the bad news.

That said, Have I Been Pwned won't tell you exactly what of your information has been leaked. It's a warning system, not a dark web data directory. So, even if, as is likely, your data is in there, it won't tell you if your SSN is in the data. 

There's also no guarantee that your leaked data is actually correct. Take me, for example, I have an unusual last name and companies are always misspelling it. Troy Hunt, the person behind Have I Been Pwned, said in his report on the NPD breach that while his email was in there, "clearly, none of the other data is mine. Not my name, not my address, and the obfuscated numbers definitely aren't familiar to me."

Hunt also added, "There were no email addresses in the social security number files. If you find yourself in this data breach via HIBP, there's no evidence your SSN was leaked, and if you're in the same boat as me, the data next to your record may not even be correct." That doesn't mean a hacker couldn't draw a link from your email address to your SSN, but it does mean that someone can just look up email and find your SSN as easily as looking up your name and phone number in an old-fashioned telephone directory.

Also: Delete yourself from the internet with these online data removal services

Notice, I didn't say if  your data has been leaked above. I can guarantee that your data has been leaked. With one data breach following hot on the heels of another for decades now, there's no question that some of your personal data is out there. 

For example, I take security more seriously than many people do, and I'm better equipped than most of you to deal with security and privacy issues. Nevertheless, my data has been ripped off in no fewer than 34 data breaches, according to Have I Been Pwned. 

Now, the vast majority of these breaches are relatively harmless. For example, my chess.com account's email address was revealed. I can live with that. But the USDoD data drop is another matter. 

Next, you need to determine just how bad the news really is. Check your credit reports for any unauthorized activity (and do so regularly!). Report any suspicious transactions to the credit bureaus (Experian, Equifax, and TransUnion) and consider  placing a credit freeze  to prevent new accounts from being opened in your name.

If you're concerned that your data's been being used against you, it's time to use an identity theft protection and credit monitoring service to protect yourself. ZDNET recommends Aura as the best overall such service.

It's not enough to have these services, though. 

You should also stay vigilant against phishing attacks . Be cautious of emails, texts, or calls that attempt to solicit personal information. Scammers will use your leaked data to craft convincing phishing attacks. For example, I recently got an email purporting to be from my bank, which included my address, warning that my account had been hacked and that I needed to change my password from the included link Right Now .

Also:  Stop paying for third-party antivirus software. Here's why

Anytime you get a message like that, whether it's warning you of something dreadful or promising you something that sounds too good to be true, don't trust it. Never click on links from such emails or text messages. 

What to do if you've clicked on a phishing link

If you've clicked on a phishing link, don't panic. Do, however, take these steps immediately: 

Disconnect from the internet and your local network immediately. This prevents any potential malware from spreading or communicating with malicious servers.

Back up important data to an external hard drive or a USB stick. This safeguards your information in case of data loss or corruption. 

Run a thorough antivirus check . Don't have one on your device? Then, you should download an antivirus program to another computer, transfer its installation program to a USB stick, and install it on your affected machine.

Change passwords for all your online accounts, especially important ones such as banking and credit card accounts. Use strong, unique passwords for each account, and consider using a password manager.

Enable multi-factor authentication . Activate multi-factor authentication (MFA) on your accounts whenever possible. This adds an extra layer of security.

Watch your important online accounts. If you see any suspicious activity, contact the company as soon as possible.

What to do if your SSN is compromised

Let's suppose, however, you have reason to believe that your SSN has ended up in the hands of crooks. In this worst possible scenario, you should take the following steps:

• File a report with the Federal Trade Commission (FTC) at IdentityTheft.gov . This website will guide you through the process and provide a personalized recovery plan.
• File a police report with your local law enforcement agency. While they may not be able to investigate immediately, having a police report can serve as important documentation.
• Check your credit reports for any unauthorized accounts or activity]. You can get free weekly credit reports from AnnualCreditReport.com .
• Place a credit freeze on your credit reports with all three major credit bureaus (Equifax, Experian, and TransUnion). This prevents new accounts from being opened in your name. You can also place a fraud alert on your credit reports, which requires businesses to verify your identity before issuing credit in your name.
• Review your Social Security Statement for any suspicious activity, such as unreported income.

Next, contact the Internal Revenue Service (IRS) to prevent potential tax-related fraud. Here's what to do: 

• Contact the IRS : You can reach the IRS Identity Protection Specialized Unit by calling 1-800-908-4490. This line is dedicated to assisting individuals who believe they are victims of identity theft involving their tax accounts.
• Submit an Identity Theft Affidavit: Complete IRS Form 14039 , the form used to report suspected identity theft to the IRS. You can submit it online via IdentityTheft.gov , which will forward it to the IRS, or you can download the form from the IRS website and mail it along with your tax return to the address specified on the form.
• Respond to IRS Notices: If you receive a notice from the IRS indicating that your SSN has been used fraudulently, follow the instructions provided in the notice. Typically, such notices come by snail mail. You may then be required to submit a Form 14039 or other documentation to verify your identity and resolve the issue.

This can be a long, tedious process. But, if you don't check and -- if necessary -- protect your accounts, your identity can be stolen. Recovering from identity theft is much more painful than preventing it.

Afterward, stay vigilant and continue monitoring your accounts and credit reports regularly. If you notice any suspicious activity, report it immediately to the relevant authorities and financial institutions. This is not a threat you can deal with once and then ignore. It's one that will continue for the rest of your life. 

Yes, I hate that too.

How much insurance do you really need.

How much insurance do you need to protect your family?

While life insurance isn’t the most fun topic to discuss, it is an important part of your financial planning and ultimately, the plan for your retirement . How can you determine how much insurance you truly need though?

The first question to ask yourself is: do you want or need life insurance? Since want is a very personal topic I won’t spend much time there. Rather, the question is on need. So, how does one determine if they “need” life insurance? For starters ask yourself if I suddenly passed away would that leave a financial hardship for someone who is relying on your continued finances? If yes, then you likely have a life insurance need. The antithesis would be if someone isn’t relying on your continued finances, and by that, I mean either assets or income.

For example, if you and your spouse are retired and/or have enough funds squirreled away you could retire, then truthfully you don’t have a life insurance need. You see if you passed away your significant other isn’t relying on an insurance policy to supplement your assets, as you’ve worked diligently over a lifetime to save ample assets.

Amounts Of Life Insurance

Once you determine that you need life insurance, you’ll need to determine the type and then how much. You can likely skip over the type, as most people can opt for term life insurance – but you’ll want to choose what is best for you and discuss with a financial advisor or insurance agent.

To figure out the correct amount of coverage you need, you can also work with an insurance agent or financial advisor. They will likely work backwards by determining what financial outlays you’ll need to take care of when you’re no longer here on this earth (which sounds morbid, but must be discussed). Let’s pretend that you’re currently 35 years old with two children and a single income of $200,000 per year. Your family may want to have the mortgage and college for the children taken care of if you were to die, so you’ll need to account for a mortgage (let’s say that is $400,000) plus anticipated college expenses for the two kids (let’s say $350,000), and let’s add in a student debt for the parents of $250,000.

So far, we’d want to cover at least $1,000,000 worth of life insurance coverage, just to cover student debts, future college expenses, and the mortgage. We still haven’t touched expenses for the surviving spouse, who now has no income coming in and still has children to care for – so you’d likely want to add in coverage here. You may want to add in $1,000,000 of coverage for every $50,000 of residual income that you’d like to leave behind. So if you want $150,000 per year of residual income, you’d want to plan for $3,000,000 in additional coverage. Add that to the million we’ve already added up, and now we’re at $4,000,000 of coverage on the working spouse.

Just because the other spouse isn’t working doesn’t mean that they don’t need coverage also – if they were to die prematurely the family would experience financial hardship and additional costs. You’d likely need to add in the same $1,000,000 for the debt coverage on this spouse, plus another $1,000,000 to account for approximately $50,000 per year in residual income to cover expenses such as a nanny or childcare until your children are grown.

Insurance And Retirement

While it seems like a lot to leave behind, it goes fast, and term insurance is relatively inexpensive comparatively. It’s easier to protect your family with insurance and continue to invest and also protect your retirement as best you can at the same time.

An enormous amount of sensitive information including Social Security numbers for millions of people could be in the hands of a hacking group after a data breach and may have been released on an online marketplace, The Los Angeles Times reported this week.

The hacking group USDoD claimed it had allegedly stolen personal records of 2.9 billion people from National Public Data, according to a class-action lawsuit filed in U.S. District Court in Fort Lauderdale, Florida, reported by Bloomberg Law.

What information is included in the data breach?

The class-action law firm Schubert, Jonckheer & Kolbe said in a news release that the stolen file includes 277.1 gigabytes of data , and includes names, address histories, relatives and Social Security numbers dating back at least three decades.

According to a post from a cybersecurity expert on X, formerly Twitter, USDoD claims to be selling the 2.9 billion records for citizens of the U.S., U.K. and Canada on the dark web for $3.5 million.

Since the information was posted for sale in April, others have released different copies of the data, according to the cybersecurity and technology news site Bleeping Computer.

A hacker known as " Fenice " leaked the most complete version of the data for free on a forum in August, Bleeping Computer reported.

What is National Public Data?

National Public Data is a Florida-based background check company operated by Jerico Pictures, Inc. USA TODAY has reached out to National Public Data for comment.

The company has not publicly confirmed a data breach, but The Los Angeles Times reported that it has been telling people who contacted via email that "we are aware of certain third-party claims about consumer data and are investigating these issues."

What to do if you suspect your information has been stolen

If you believe your information has been stolen or has appeared on the dark web, there are a few steps you can take to prevent fraud or identity theft.

Money.com recommends taking the following steps:

• Make sure your antivirus is up to date and perform security scans on all your devices. If you find malware, most antivirus programs should be able to remove it, but in some cases you may need professional help.
• Update your passwords for bank accounts, email accounts and other services you use, and make sure they are strong and different for every account. Include uppercase and lowercase letters, numbers and punctuation marks, and never use personal information that a hacker could guess.
• Use multifactor authentication for any accounts or services that offer it to ensure you are the person logging in.
• Check your credit report, and report any unauthorized use of of your credit cards. If you notice any suspicious activity, you can ask credit bureaus to freeze your credit.
• Be careful with your email and social media accounts, and beware of phishing, an attempt to get your personal information by misrepresenting who a message or email is from.
