COVID-19 Updates for Doctoral Students
- All classes taken by doctoral students in Winter 2020, including RCC courses, will be accepted for degree credit if a 'Satisfactory' grade is earned. Students are not required to unmask their grades, though may do so if they choose.
- Students intending to take the DPE during the Winter 2020 or Spring/Summer 2020 terms are encouraged to do so remotely using BlueJeans or Zoom.
- As needed students scheduled to take the Fall 2020 RFE will be allowed to delay the exam until Winter 2021. This is as a result of slowed research progress in the spring and summer of 2020.
The goal of the PhD program is to create a culture of scholarship and high impact research that produces articulate researchers who are called upon first to hold leadership positions in society and academia.
The Doctor of Philosophy (PhD) Degree is the highest degree awarded by the Mechanical Engineering Department and is recommended for students who are interested in leadership careers in academia (e.g. as a faculty member of a university), industry, or government.

Ph.D. Research at the University of Michigan
Research involves active, student-directed inquiry into an engineering topic. A student’s research experience forms the core of the PhD program. There are two goals for conducting research: 1) to learn the general skills to conduct independent research and 2) to develop new knowledge in mechanical engineering.
Conducting research requires combining knowledge gained in the classroom with the ability to read the scientific literature, identify critical knowledge gaps, structure complex problems, formulate and test hypotheses, analyze and interpret data, and present and discuss technical results. Engineering research also requires significant experimental, computational, and analytical skills. A student learns these core skills as she pursues her research topic.
Many of these skills cannot be learned in the classroom setting, but instead must be developed in the laboratory, library, and conference room as the student actively interacts with faulty, other students, and researchers around the world. Independent, non-classroom based learning and problem solving is a core aspect of the PhD degree. Upon completion of his dissertation the student should be an international expert in a technical area. Dissemination of new knowledge at technical conferences and in peer-reviewed archival publications is an important part of research.
There are three student profiles in the ME PhD program: (1) Direct PhD students that are admitted without a relevant Master's degree, (2) students who enter the PhD program with a Master’s degree in Mechanical Engineering or a relevant field, and (3) students who enter the PhD program with a Master's degree in Mechanical Engineering or a relevant field from the University of Michigan. The differences in the three tracks toward the PhD vary at the coursework level. Please be mindful of the requirements listed below. A student should always discuss academic plans with his research advisor.
The major ME program milestones all PhD students complete:
- Research and Coursework
- Qualifying Examination (RCC & RFE)
- Advancement to Candidacy
- Dissertation Proposal Examination
- Thesis Dissertation (written) and Defense (oral)
In addition to the academic component of the PhD, students are encouraged to participate in professional development. The Rackham Graduate School has partnered with divisions around campus to develop a central location to promote workshops, training sessions, forums, and talks relevant to graduate students. It is recommended that students visit the Professional and Academic Development website on a regular basis to stay informed about the activities on campus.
Timeline & Satisfactory Progress
The timeline for completing these milestones and other program requirements and expectations.
To continue in the Ph.D. Program and remain fully funded, you must maintain satisfactory progress in the following ways:
- Maintain Cum. GPA of 3.5 or higher
- Engage in research with faculty by the end of 1st semester.
- Solidify faculty advisor by the end of 1st semester.
- Identify thesis topic by the end of 2nd semester.
- International students must take and pass the GSI OET by the end of the 3rd semester.
- Pass the RCC by the end of 2nd semester (an extra semester may be granted via petition if necessary, but no more).
- Demonstrate preliminary results in research by the end of the summer term after the first year (in preparation for the RFE). If you have concerns about your progress, email the Grad Coordinator to schedule a meeting with Grad Chair.
- Pass the RFE by the end of 4th semester. Change-of-Program students pass the RFE within two semesters of beginning the Ph.D. Program. An extra semester may be granted in either case via petition if necessary, but no more.
- Complete Dissertation Proposal Exam (DPE) and form dissertation committee within one year of passing the RFE. (For students who take the RFE in their 3rd semester, it is desirable to complete the DPE by the end of the 2nd year in the PhD program.)
- Maintain progress toward publications and dissertation completion with the guidance of advisors. If you have concerns about your progress, email the Grad Coordinator to schedule a meeting with Grad Chair.
You are welcome and encouraged to speak to the Graduate Coordinator and Chair at anytime. You and your advisor both have opportunities to confirm progress or express concerns regarding your progress via the Annual Progress Update.
Probation: If a student is not making satisfactory progress in one or more of the areas outlined above, the student will be put on probation. The terms of probation will be individually designed based on the student's situation and as agreed upon by the Graduate Program Committee (GPC), the Graduate Chair, the faculty advisor, and the student. When a the terms of probation are agreed upon, a probation agreement will be completed and enforced by the Graduate Chair.
Length of the Probationary Period: The probationary period will be no shorter than two months and, unless otherwise stated, conclude at the end of that term. If a student is placed on probation within two months of the end of the term, the probationary period will extend into the following term for at least two months.
Funding During the Probationary Period: Doctoral students will continue to receive funding during the probationary period.
End of the Probationary Period: At the end of the probationary period the student will either be returned to good academic standing or dismissed from the program.
Appeals Process for Probation and Dismissal: Students may appeal academic probation or dismissal decisions. Appeals pertaining to a students’ academic performance or progress in the program will be overseen by the Graduate Program Committee. The Rackham Graduate School will handle appeals relating to procedural issues of fair and equal treatment by the program.
Finding a Research Advisor:
To select a research advisor, the student should talk to faculty members in potential areas of research interest. If the research topic is of an interdisciplinary nature, the student can choose to have two research advisors as long as at least one advisor is from Mechanical Engineering. Recommendations and tips for finding a research advisor:
- Talk to senior graduate students about their advisors. Share your interests and ask them for suggestions about whom you should meet.
- Familiarize yourself with various research groups.
- Make a list of faculty to contact who are involved in research areas that interest you. A list of faculty by research areas can be found here.
- Read about faculty research in journals, conference proceedings, or on their website.
- Visit their labs. A list of labs can be found here.
- Schedule meetings with faculty members. Typically this is done via email which includes an introduction and requests time to meet with them. Be knowledgeable about their work in order to have an active discussion about their previous and ongoing research.
- Sometimes working in their lab for academic reasons only (not as a Graduate Student Research Assistant (GSRA) ) will provide you with the opportunity to prove your researching capabilities and may lead to a GSRA with that faculty.
- If possible, enroll in classes being taught by faculty whose work interests you.
- Do well in classes relevant to your research interest and get to know the faculty.
- Consider doing a small project supported intellectually by a faculty member. ME 590 research credits are taken.
- If you are unsuccessful with securing a research advisor, it is recommended that you meet with the Graduate Program Chair immediately to discuss the situation.
Regardless of whether or not the Ph.D. student has a Master's prior to attending U-M or not, all students should take at least 6 credits of research (ME 590) in the first two-three terms of the PhD program. This will help ensure that the student meets Rackham's requirements to candidacy upon successfully passing of the qualifying exams. Change of Program students are not required to enroll in addition ME 590 credits after matriculating to Ph.D. as they have already completing the credit requirement for advancing to candidacy.
Students should complete 8 hours of responsible conduct of research and scholarship (RCRS) training by the end of their 3rd term of enrollment.
Once a student has completed 6 credits of ME 590, they should take 8 credits of ME 990 per term.
Once a student reaches Candidacy, 8 credits of ME 995 research credits are taken every term until the student defends their dissertation.
For Direct PhD students (i.e. students admitted without a relevant Master’s degree):
- It is necessary to complete all of the academic requirements for the Master’s degree which includes 30 credits. Please visit the Master's Degree page for specific degree requirements. This type of Master's degree is referred to as an "embedded" master's, a master's degree awarded "on-the-way" to the PhD. In addition to their MSE degree, direct PhD students must complete:
- At least 6 credits of letter-graded (including the grade S - Satisfactory) graduate coursework registered as a Rackham student while in residence on the Ann Arbor campus. Courses elected as visit (audit) do not meet this requirement, nor do ME590, ME695, ME990 and ME995.
For PhD students entering with a relevant Master's Degree:
- At least 18 credits of letter-graded (including the grade S - Satisfactory) graduate coursework registered as a Rackham student while in residence on the Ann Arbor campus. Courses elected as visit (audit) do not meet this requirement, nor do ME590, ME695, ME990, and ME995.
- Of the 18 letter-graded credits, 4 credits must be cognates. The cognate requirement may be satisfied by having completed a UM Master’s degree which included a cognate component.
- A PhD student entering with a relevant Master's degree that decides to pursue an additional master's degree at the University of Michigan may apply the 18 credits required for the PhD to the master's degree in another department. The student's advisor should approve of the second degree.
For PhD students entering with a Master's Degree from the University of Michigan (i.e. change of program students):
- At least 6 credits of letter-graded (including the grade S- Satisfactory) graduate coursework registered as a Rackham student while in residence on the Ann Arbor campus. Courses elected as visit (audit) do not meet this requirement, nor do ME590, ME695, ME990, and ME995.
For students who completed the SUGS program:
- At least 6 credits of letter-graded (including the grade S- Satisfactory) graduate coursework registered as a Rackham student while in residence on the Ann Arbor campus. Courses elected as visit (audit) do not meet this requirement, nor do ME590, ME695, ME990, and ME995.
- Additional credits of letter-graded graduate coursework equal to or greater than the number of credits double counted in the SUGS program.
The PhD Qualifying Examination (QE) consists of two components: the Research Core Curriculum (RCC) (formerly GCC) and the Research Fundamentals Exam (RFE).
Research Core Curriculum (RCC) Exam
The goal of the RCC is to ensure proficiency in technical topics both within and outside of the student's primary research area.
All PhD students must take four Research Core Curriculum (RCC) courses in the first two semesters. Typically students will enroll in two Research Core Curriculum courses in the first term, however some exceptions exist where students will only enroll in one or will opt to take three. During the second term of study, the remaining Research Core Curriculum courses are taken. Change-of-program students should refer below.
The RCC consists of four 500+ level graduate courses that satisfy the following course distribution requirements:
- At most, three may be in the student’s research area
- At least one must be outside of the student’s research area
- At most, one may be from a department other than Mechanical Engineering. Note: Multiple cross-listed courses in the RCC plan will prompt additional consideration by the Graduate Program Committee (GPC)
In consultation with their research advisor a student should develop and submit a RCC plan. If a student does not have a research advisor, the student should submit a preliminary RCC plan by the Friday before the first day of classes. The ME Graduate Chair will then work with the student (if necessary) to arrive at a satisfactory plan. An RCC Plan is comprised of the following components:
- A list of the four courses on which the RCC will be based (a list of all ME graduate-level courses scheduled for the Fall and Winter terms is located here).
- A short (3-4) sentence statement that specifies how the courses fit into the student's current or intended research plan (this can be general if the student does not yet have a research advisor).
- The approval of the student’s research advisor and/or the ME Graduate Chair.
The GPC will review and (if appropriate) approve RCC course plans based on their accordance with the course distribution requirements specified above and their academic rigor. The GPC will monitor the historical record of GPAs for courses selected on the RCC, and may ask a student to revise the student's RCC plan if the plan is judged to be insufficiently rigorous.
RCC plans may need to change after the start of the semester or between the first and second semester of the RCC. Typical circumstances that may necessitate a revision include course cancellations and a change in the student's research area and/or research advisor. Revised RCC plans require GPC approval. Requests for modifications to RCC plans should be submitted via the RCC form prior to the add/drop deadline for the term..
GPC approval is required for dropping a course after the above dates and will only be given in rare circumstances. Changes in research area and/or research advisor are not sufficient reasons for dropping an RCC course.
Evaluation of the RCC (for those who entered the PhD program after Winter 2014): The grades students receive in RCC courses will be averaged to determine an RCC GPA. The GPA is based on Rackham's new 4.0 scale where A+ = 4.3 , A = 4.0, A- = 3.7, and B+ = 3.3. The RCC GPA will be used to determine the outcome of the RCC and will follow these guidelines:
|RCC GPA||RCC Outcome||RFE Stipulation|
|≥ 3.7||Pass Unconditionally||--|
|≥ 3.5 - < 3.7||Conditional Pass||Strong RFE Pass*|
|< 3.5||Fails Unconditionally**||--|
*Note: A student must demonstrate proficiency by performing very well on the RFE (as judged by the RFE examiners) to pass the PhD qualifying examination. The student has two tries on the RFE to perform very well.
**Note: The student may petition the GPC to take an additional course in the third semester if that course grade could increase the overall GPA (of all five courses) to at least a 3.5 (or a 6.5 via the old Rackham 9.0 scale).
Petitions for a deviation from the above guidelines due to rare and extenuating circumstances can be made to the GPC. There are no course retakes in the RCC.
Change-of-Program Students. The GPC will evaluate the prior courses taken by a change-of-program (i.e. MSE to PhD) student to determine which (if any) courses may be eligible to include in an RCC plan, thus reducing the total number of RCC courses required to be taken after the student enters the PhD program. In some cases, a student's previously completed coursework may satisfy the RCC entirely; thus, the student would not be required to take any additional coursework.
Research Fundamentals Exam (RFE)
The RFE is an oral examination to test the student's potential to conduct independent research at the PhD level along with her written and oral communication skills. There are four primary objectives:
- Assess the depth of knowledge in the area of research specialization and the ability to relate this to research,
- Assess the ability of the student to propose an interesting and relevant problem for PhD research
- Test ingenuity, creativity, and problem-solving skills, and
- Assess written and oral communication skills and the ability to respond to questions.
Students who have a research advisor and have successfully completed the RCC coursework or who have successfully petitioned are eligible to apply for the RFE. Students must have a 3.5 GPA or higher to take the RFE. If a student does not have this GPA, they are required to submit a petition form to the graduate chair for consideration to take the RFE.
PhD students who successfully complete the RCC coursework must take the RFE the following semester. Change of Program students must take the RFE within one year. It is not mandatory for Change of Program students to take the RFE in their first semester as a PhD student.
Exams are held in the last two weeks of October and last two weeks of March (winter). The RFE is an oral exam lasting for 45 minutes which is structured with a 15 minute presentation followed by 30 minutes of question and answer with two faculty members.
The RFE is organized by research subject areas as listed below:
|Dynamics & Vibrations||Solid Mechanics|
|Fluid Mechanics||Thermodynamics and Combustion|
Registration. Eligible students must register their intent to take the RFE to the Academic Services Office. The online registration form is announced to students via email in the first two weeks of each Fall and Winter semester. In addition, students are responsible for submitting an electronic document with the following elements:
- Bio-sketch using NSF fellowship application format,
- Research abstract describing research: the purpose of the research being examined, key related research, research hypotheses, research methodology, and results to date. The abstract should be formatted with 11 point font, single spacing, one-inch margins, and be a maximum of 2 pages. These two pages include citations and bibliography.
- A list of RCC courses with discussion of how the RCC courses match the RFE topic and future research plans (less than 200 words).
Examiners. Two faculty are selected by the Graduate Program Committee to act as examiners for each RFE thematic area. A student's research advisor cannot be an examiner. The research advisor is not allowed to be present during the RFE.
Grading. Students are evaluated on a scale ranging from excellent to poor in each of the following areas:
- Synthesis of course material in research problem context.
- Input to research project.
- Research conduct and methodology.
- Research outcomes.
All areas are considered when determining the student's examination outcome (pass/fail). The two examiners will produce a written report to the Academic Services Office indicating if the student has passed or failed the RFE with specific reasons for their decision.
Communication of Results. The result of the RFE is communicated by the Academic Services Office to the student by way of individual email. Successfully completing the RFE does not mean a student passes the RCC.
Retaking the RFE. Only one repeat is permitted and must be taken no later than the next offering of the RFE after the original RFE. Students will automatically be sent a registration email for the next available RFE session.
Advancing to Candidacy is a prestigious milestone on the way to the PhD. Rackham stipulates that from the time of initial enrollment, Candidacy should be achieved within 3 years. There is reduced tuition associated with candidacy as well as registration constraints.
Semester deadlines for completing the requirements to advance to candidacy are found here.
Requirements to advance to candidacy:
- Pass the Qualifying Examination (RCC and RFE)
- Completed at least 18 credits of letter-graded (including the grade S - Satisfactory) graduate coursework registered as a Rackham student while in residence on the Ann Arbor campus. Credits elected as visit (audit) do not meet this requirement, nor do any ME990 or ME995 credits.
- Of the 18 credits, 4 must be cognates.
- Completed RCRS training requirement. Workshop Schedule can be found here.
Upon successful completion of the RFE, students will automatically be advanced to candidacy if they have met all of the requirements listed above. If a student does not wish to advance to candidacy, they should note that on the RFE registration form or notify the Graduate Coordinator in advance (email@example.com).
Rackham's Free Course Policy:
"Ph.D. candidates register in the fall and winter terms for 995, “Dissertation/candidate,” which consists of 8 credit hours for a full term or 4 credit hours for a half term. No part-time enrollment is possible. A student who defends in the spring/summer term must register for 8 credit hours of 995 for the spring/summer full term.
Candidates who register for a course should seek prior approval from their faculty advisors. Candidates may elect either one course per term or more than one course for a total of no more than four credits without paying additional tuition beyond candidacy tuition. Courses may be taken for credit or as a visit (audit). A candidate who does not elect a course during a term of 995 enrollment may, in the next term, either register for courses for no more than 8 credits or register for no more than two courses that total more than 8 credits. An additional course may not be taken in anticipation of taking none in a future term of 995 enrollment. Candidates who choose to take more courses than those for which they are eligible will be assessed additional tuition per credit hour." Original Source.
GSI Oral English Test (OET) Requirements for International PhD Students
GSI Oral English Test (OET) is used to review the English proficiency of international students. Passing the exam is a requirement for international PhD students and is necessary to ensure satisfactory progress while simultaneously confirming the ability of that student to be an effective GSI. All international students must pass the OET by the end of their 3rd academic term after admission (e.g., by the end of F12 for students who entered in F11) in order to be considered making satisfactory progress toward their degree. International students whose undergraduate education was taught exclusively in English may be exempt from the OET. Additional exemption criteria can be found here.
- Upon successful completion of this requirement, the student will then be eligible to hold a GSI position (see the English Language Proficiency Requirements section).
- If the student does not hold a GSI position within the next 18 months after passing the exam, the student must check in with the English Language Institute (ELI) to extend or renew their exam results. In order to continue making satisfactory progress, a PhD student must maintain valid exam results throughout their academic tenure. Please contact the English Language Institute to schedule a renewal interview.
- The ELI will evaluate the student's English skills and determine if the student is qualified to extend the exam results or is required to retake the exam. It is the student's responsibility to contact the ELI to maintain valid exam results.
The DPE is an oral exam that provides an early assessment of the feasibility of a student's proposed research topic for his/her dissertation. In particular, the exam is intended to assess the suitability of the topic and the student's academic background for carrying out the proposed research. The exam is administered by a student's Dissertation Committee. The DPE should be completed within one year of passing the RFE.
The Dissertation Committee
Students will assemble their dissertation committee prior to taking the DPE. The Dissertation Committee oversees the student's research outcomes. Through the dissertation proposal exam, committee meetings, and the thesis defense, the committee tracks the student’s progress and provides feedback and guidance. At each of these meetings, the student presents his research and responds to the committee members’ questions. The purpose of the committee is to provide an outside perspective on the student’s research, helping the student to structure his/her work and identify opportunities. The committee is responsible for approving the student’s research plan via the DPE and signing off on the final dissertation and defense.
Dissertation Committee Requirements:
A committee must have a minimum of 4 members:
- The chair or one of the co-chairs should be a member of the faculty in the Mechanical Engineering department.
- Three members must be from a Rackham Doctoral Program and be considered a member of "The Graduate Faculty", this generally means a Professor at the University of Michigan.
- Two members must be from the Mechanical Engineering department.
- One member must have a 50% appointment in a Rackham doctoral program, other than the Mechanical Engineering department (except Interdisciplinary programs) - otherwise known as your cognate member.
The committee may include a University faculty member who is not a member of "The Graduate Faculty", a University staff member, or a qualified individual outside the University who to provide expertise in the candidate's discipline. Any non-faculty member must be approved by the Graduate Program. These special members require additional documentation to be submitted, ideally prior to the DPE.
The Rackham Graduate School has also developed a Quick Reference Chart for Eligibility to Serve on Dissertation Committees.
Once the committee is formed, the DPE is scheduled as the first meeting of this committee. The student will prepare a written thesis proposal for the committee to review and give an oral presentation to the committee. The format of the written thesis proposal as well as the timing of the exam is at the discretion of the committee chair.
Upon completion of the DPE, the committee chair prepares a memorandum addressed to the ME Graduate Program Chair. The memo should state the outcome of the DPE and list the dissertation committee members. (Example memo here) The signed memo is submitted to the Graduate Coordinator (firstname.lastname@example.org). This information will be used to formally process the student's dissertation committee with the Rackham Graduate School.
After the Graduate Coordinator has submitted the dissertation committee to Rackham Graduate School:
- The student and committee chair will receive automatically generated emails to approve of the committee submission.
- Rackham will then approve of the dissertation committee ensuring that all requirements are met.
- Once approved by Rackham, the student and the Graduate Coordinator will receive confirmation that it has been approved. At this time the committee information will be visible in the student's record in Wolverine Access.
The official guidelines for the dissertation and defense are established by the Rackham Graduate School. In addition, the Rackham Graduate School publishes annual deadlines by which a candidate must defend a dissertation and complete all degree requirements as set forth by Rackham. Doctoral students are expected to complete the degree within 5 years of achieving candidacy, but no more than 7 years from first enrollment.
Dissertation (Written). The dissertation is the most important aspect of the students PhD program experience, since it documents the original contributions made by the candidate as a result of independent research. In advance of graduation, the dissertation must be approved by all the members of the student's dissertation committee. The student will prepare a rough draft of the dissertation and provide it for all the committee members for their comments before preparing the final draft. Students must provide the rough draft to the committee at least 10 days before the Defense.
Defense (Oral). The defense examination will be given after the thesis has been formally completed. This examination will be a defense of the doctoral thesis and a test of the candidate's knowledge in the specialized field of research. The format of the examination will be a public seminar presented by the candidate, with an open question period, followed by a private examination by the Dissertation Committee.
Thesis Dissertation and Defense Timeline:
After the dissertation committee gives preliminary approval to the final draft of the dissertation, it must be formatted to meet the standards of Rackham Academic Records and Dissertations (OARD) found here. Support for thesis formatting is available from the Knowledge Navigation Center in the Graduate Library, which offers tutorials, template assistance, guides, and resources for dissertation preparation.
Before the oral defense, students are required to set up a pre-defense meeting with the Rackham Graduate School. In this meeting, students will be instructed on the process and be given Dissertation Evaluation Forms. When the final draft is distributed to the committee members together with Dissertation Evaluation Forms, a defense (oral) is scheduled for a date approximately two weeks later. Dissertation Evaluation Forms must be completed by all Dissertation Committee members at least three working days prior to the oral defense. The defense is public, and a notice is posted on the Rackham Graduate School website, and the Academic Services Office will send an email announcement to the ME students and faculty. After the oral defense, the student or committee chair should submit the Final Oral Examination Report within 48 hours of the defense. The student should then attend the post-defense meeting with the Rackham Graduate School.
