The primary objective of the PhD degree program is to educate students to the highest levels of their chosen field to enable them to make lasting impacts to fundamental knowledge, technology, and society through research. PhD students are expected to become domain experts and complete research that can withstand the rigorous test of external peer review.
We offer funding to all PhD applicants whom we admit. Our department anticipates extending full funding to about 70 Fall 2024 PhD applicants. Funding includes:
- a graduate student salary,
- tuition remission,
- mandatory student fees, and
- 91% health insurance coverage.
In your first year, you will be funded by the department as a Teaching Assistant (TA) for one semester and as a Research Assistant (RA) for the other semester, which enables you to find a research lab and to practice working in a classroom setting. Faculty with alternate sources of funding may petition the department to waive the TA requirement for first year students in their lab. In your second year and beyond, you will be funded by a research advisor as an RA or through other fellowships, pending reasonable research progress and academic performance. If your research advisor has a funding gap, they can apply to the department for gap funding. This way, students have a safety net so that they can continue to be funded throughout their PhD program.

PhD Courses Requirement
PhD students must complete a minimum of 30 graduate-level credits at the 5000 level or higher. Of these 30 credits, at least nine must be mechanical engineering department courses. All PhD students are required to take the following courses:
- MCEN 5020: Methods of Engineering Analysis (3 credits)
- MCEN 5030: Introduction to Research (3 credits)
Note: Some faculty research advisors will require that their students complete more than 30 course credits. The department recommends that students consult with both their graduate program advisor and faculty research advisor for guidance on coursework recommendations or requirements.
Mathematical Proficiency Requirement
All PhD students are required to take MCEN 5020 Methods of Engineering Analysis and to pass with a grade of B- or higher. Students receiving a grade below B- in MCEN 5020 must retake the course. PhD students will not be able to advance to post-prelim status until the mathematical proficiency requirement has been completed. Failure to complete this requirement by the end of the second year of the PhD may result in removal from the PhD program.
Dissertation Hour Requirement
In addition to coursework, you are required to complete 30 dissertation hours. Students are not able to register for thesis credits on their own and should schedule an appointment with their graduate advisor to be registered. Students must continuously enroll in five dissertation credits in the semesters following passing the comprehensive exam.
Fundamental Topics Preliminary Exam
All PhD students must successfully pass the fundamental topics preliminary exam, which is intended to assess the potential to successfully complete a PhD in mechanical engineering. It is designed to evaluate analytical skills, appraise knowledge of mechanical engineering fundamentals, and to gauge potential for creative independent research. The exam requires students to consolidate their grasp of the fundamentals of mechanical engineering and to demonstrate an aptitude for communicating knowledge during an oral presentation. The content of the examination reflects consensus across the department faculty. The examination is administered by the Graduate Committee, acting on behalf of the entire faculty.
Research Preliminary Exam
The research preliminary exam is an oral presentation of research to a committee of three that must include a PhD student’s research advisor and at least one other faculty member from mechanical engineering. Students should view this as an early thesis proposal. At least one week prior to the exam, students must send a 250-word presentation abstract, including title and any relevant references, to all committee members.
Comprehensive Examination
Students must complete a comprehensive exam between 6 and 12 months prior to defending their PhD dissertations. At the time of the comprehensive exam, the dissertation committee will be formed and given preliminary approval by the Department and Graduate School. A mechanical engineering PhD degree requires depth of knowledge in the dissertation/research area, as well as breadth of knowledge across the mechanical engineering curriculum. Consequently, the comprehensive exam is designed to test student knowledge of their proposed research area, and any general knowledge in the field. It is also intended to evaluate whether a student’s proposed research project is original and creative work, whether it will make a significant impact in the field, and whether it will qualify for publication in quality peer-reviewed journals. The exam is also an opportunity to demonstrate an ability to present scientific concepts orally. In short, the comprehensive exam serves as the gateway to the next phase of the doctoral program: completion of a dissertation.
Written Dissertation
The written dissertation must comply with Graduate School rules and procedures in terms of format and submission. The dissertation title appears on official university transcripts and must be submitted to the Graduate School in addition to the physical signature page from the dissertation. Students are also required to submit the full written dissertation electronically at the ProQuest website.
Dissertation Defense
Before completion of the PhD degree, students must have their dissertation accepted for defense by the review committee. The dissertation defense may occur before or after the final electronic submission of the written dissertation to the Graduate School, but must take place prior to the end of the final semester of enrollment. Students must then pass a dissertation defense, which is a final examination on the dissertation and related topics. In the defense, students are expected to explain their research clearly and concisely, and to discuss how it relates to other research in the field. This is an opportunity for recognition of completed doctoral work. It is also an opportunity for discussion and formal evaluation of the dissertation.
