Any courses listed on our courses page will fulfill this requirement, including available non-engineering courses.  

All questions regarding courses and transfer credits should be directed to a student’s academic advisor.  

Items of Note:    

• Transfer credits from a student’s Master’s degree will be evaluated and applied to specific components of the degree. Students will utilize ENGR 60100: Doctor of Engineering Fundamentals to propose how a previous master’s degree could be applied to D.Eng. degree requirements.  
• Minimum credit requirements allow for maximum flexibility and the ability to tailor your degree plan to your specific areas of interest and goals. After you begin your studies at Purdue, an academic advisor will provide you with tools to map out a plan of study tailored to align with your specific goals.  

  Dissertation    

The dissertation demonstrates the candidate’s ability to conduct substantial and significant research in the engineering discipline(s) selected. Candidates are expected to demonstrate mastery of the key literature in the field and use this to situate the specific project they propose. Students enroll in a College of Engineering doctoral research course to complete and receive credit for their dissertation research. Students are required to complete a minimum of thirty credit hours of doctoral research, a requirement that will be distributed across multiple semesters. The exact duration of this distribution depends on the individual student's progress in their dissertation research. In most cases, it is expected that a student will use their final one or two years to formulate the research topic, develop the proposal, and conduct self-directed research under the guidance of their faculty advisor and with the hopeful support of an industry partner and advisor—likely the student’s full-time employer.  

At the conclusion of their program, or in the final semester, students will have a final oral defense of their dissertation research before a graduate committee of reviewers.  

Distinction between a PhD and a professional Doctorate degree    

A PhD in Engineering is earned by demonstrating research independence in an engineering-related field of study and generation of new knowledge. A Doctor of Engineering is earned by completion of interdisciplinary professional coursework and demonstration of research independence in an engineering-related field of study, and direct application of the research to engineering practice in real-world, industry, commercial, defense, or other areas of operation and utilization.    

In each program, dissemination of knowledge is key to the training, but may differ depending on the context of each student’s unique context (i.e. presentations at scientific or trades conference, white papers, internal reports, peer-reviewed manuscripts in archival journals, book chapters).

Tips and Examples for Writing Thesis Statements

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Tips for Writing Your Thesis Statement

1. Determine what kind of paper you are writing:

• An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
• An expository (explanatory) paper explains something to the audience.
• An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.

If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.

2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.

3. The thesis statement usually appears at the end of the first paragraph of a paper.

4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.

ENHANCING VISUAL UNDERSTANDING AND ENERGY-EFFICIENCY IN DEEP NEURAL NETWORKS

Today’s deep neural networks (DNNs) have achieved tremendous performance in various domains such as computer vision, natural language processing, robotics, generative tasks etc. However, these high-performing DNNs require enormous amounts of compute, resulting in significant power consumption. Moreover, these often struggle in terms of visual understanding capabilities. To that effect, this thesis focuses on two aspects - enhancing efficiency of neural networks and improving their visual understanding. On the efficiency front, we leverage brain-inspired Spiking Neural Networks (SNNs), which offer a promising alternative to traditional deep learning. We first perform a comparative analysis between models with and without leak, revealing that leaky-integrate-and-fire (LIF) model provides improved robustness and better generalization compared to integrate-and-fire (IF). However, leak decreases the sparsity of computation. In the second work, by introducing a Discrete Cosine Transform-based novel spike encoding scheme (DCT-SNN), we demonstrate significant performance improvements, achieving 2-14X reduction in latency compared to state-of-the-art SNNs. Next, a novel temporal pruning method is proposed, which dynamically reduces the number of timesteps during training, enabling SNN inference with just one timestep while maintaining high accuracy. The second focus of the thesis is on improving the visual understanding aspect of DNNs. The first work along this direction introduces a framework for visual syntactic understanding, drawing parallels between linguistic syntax and visual components of an image. By manipulating images to create syntactically incorrect examples and using a BERT-like autoencoder for reconstruction, the study significantly enhances the visual syntactic recognition capabilities of DNNs, evidenced by substantial improvements in classification accuracies on the CelebA and AFHQ datasets. Further, the thesis tackles unsupervised procedure learning from videos, given multiple videos of the same underlying task. Employing optimal transport (OT) and introducing novel regularization strategies, we develop the ‘OPEL’ framework, which substantially outperforms existing methods (27-46% average enhancement in F1-score) on both egocentric and third-person benchmarks. Overall, the dissertation advances the field by proposing brain-inspired models and novel learning frameworks that significantly enhance the efficiency and visual understanding capabilities of deep learning systems, making them more suitable for real-world applications.
