PhD in Mechanical Engineering

The Department of Mechanical Science and Engineering boasts a world-class program leading to the PhD in Mechanical Engineering, offering tremendous flexibility in course selection.

Students may choose whether or not to earn the MS on the way to earning the PhD in Mechanical Engineering. Most students joining the department enter the PhD program in Stage 1, during which students complete their MS degree in Mechanical Engineering or Theoretical and Applied Mechanics. An outline of the steps toward completion of the Mechanical Engineering PhD is presented below.

Stage 1: MS or its Equivalent

Please select a link for information on getting your MS degree in ME & or TAM.*

Students entering directly after earning the BS are considered Stage 1 PhD students until the prerequisite for the qualifying exam has been completed. 

Stage 2: Qualifying Examination, PhD Coursework, Preliminary Examination

The Department requires graduate students to successfully complete a qualifying examination to formally enter the PhD program.

ME PhD Qualifying Examination

The objective of the qualifying exam is to evaluate student’s sufficient depth and breadth of understanding in the area of research. Towards this goal, a committee of two faculty members appointed by the Associate Head for Graduate Programs for each examinee will administer an hour-long oral exam on a peer-reviewed, archival journal article related to student’s area of research. The committee will be asked to select an important paper in the student’s research field, consistent with the fact that the student has a two-week preparation period.  The paper is chosen by the committee in consultation with the student’s advisor, and is provided to the student two weeks ahead of the exam. The article may not be one authored/co-authored by the student or by any faculty in the department.  The exam result is presented as pass, conditional pass or fail, and should be submitted via email to the Graduate Programs Coordinator.  The Assistant Director of Graduate Programs will relay the result to the student’s advisor.

A minimum of B+ grade in each of four independent courses from any one or a combination of any two areas chosen from an approved list (see below) is a prerequisite for taking the qualifying exam.

A student may attempt the examination twice.

Details of the Exam

Prerequisites:  A B+ grade or higher in each of the four independent courses chosen from an approved list (see below) is a prerequisite for appearing in the qualifying exam. These four courses can be chosen from a single area or a combination of any two areas. In addition, the student is required to take the qualifying exam within two years after a master’s degree or within three years of a bachelor’s degree. The advisor must approve the choice of courses. Students would be encouraged to retake a class to improve their grade sufficiently to meet the requirements. Transferred coursework cannot be used to fulfill the prerequisites of the qualifying exam.

Administration of the Qual Exam:  Students who have satisfied the prerequisites for the exam and wish to register should submit the ME PhD Qualifying Exam Form to the Graduate Programs Office. Exam schedules will be set based on committee availability and must not be earlier than 3 weeks from the time of the request approval.

Advisors will email the names of three suggested committee members and three suggested articles to the Graduate Programs Office.

The Associate Head for Graduate Programs will review the request and select the two members for the evaluation committee.

A notice will be sent from the Graduate Programs Office to the committee, informing them that they have been appointed to administer the examination and who has been named Committee Chair. The notice will also include the suggested articles from the advisor and the timeline in which the exam needs to be scheduled.

Students are responsible for picking a date and time that works for all committee members. Once a date and time are confirmed by all committee members, students must email mechse-grad@illinois.edu the date and time of their exam, with each member of the committee carbon-copied (CCed) on the email. 

Oral Examination Committee:  A committee of two faculty members from MechSE appointed by the Associate Head for Graduate Programs for each examinee will administer an hour-long oral exam on a peer-reviewed, archival journal article related to student’s area of research.

Journal article: The student will be examined on a published, peer-reviewed archival journal article related to student’s research. The student’s adviser will provide a suggested list of papers to the Graduate Programs Office with a rationale for the choice of the articles, to be shared with the examining committee.  The committee may choose a paper from the list, or it can choose a paper outside of the advisor’s suggested list, but from within the general research area of the student.  The selected paper must be an important paper in the student’s research field, consistent with the fact that the student has a two-week preparation period. If the article selected is outside the list, the committee needs to provide a rationale for the choice of the article, and a statement describing the reason as to why an article was not chosen from the advisor’s suggested list. The committee’s statement will be provided to the Associate Head (AH) for Grad Programs, and not to the student’s advisor. AH may communicate the statement to the advisor at his/her own discretion. The article may not be one authored/co-authored by the student or by any faculty in the department. In addition to reading the article, the student is expected to review the related literature. The article will be provided to the student two weeks ahead of the exam, so please contact the Graduate Programs Office with the article selection as quickly as possible. Once the paper is selected, the student will be notified to contact the committee to schedule the examination.

Grading: The student must present the material from the article in 30 minutes, and answer committee’s questions in the remaining 30 minutes. The exam will be graded on the following points:

  • overall significance of the article
  • influence of the work on the development of the field
  • possible future research directions in the area of the article
  • the key findings of the work
  • connection to student’s research

Outcome of the exam: the result can be (a) an unconditional pass, (b) a conditional pass pending taking a specific course or courses with a defined minimum grade, and (c) a fail. On failing, a student may repeat the oral exam once.

Preliminary and Final Examinations

Scheduled upon completion of coursework requirement or in the semester in which the final coursework is taken. To schedule your exam, please see this page on the Graduate College website: grad.illinois.edu/thesis/submitting-doctoral-committee-requests 

You should submit your exam request to the Graduate College at least 3 weeks prior to the approximate exam date. Once you have submitted your Graduate College exam request, a notice is sent to the MechSE Graduate Programs  Office to approve the request. Once the request is approved by the MechSE Graduate Programs Office, the Graduate College will send the student and the MechSE Graduate Programs Office notice that the exam has been approved. 

After the Graduate College has approved your exam and you have been notified of the approval via email, the MechSE Graduate Programs Office will direct you to complete the Departmental Preliminary Exam Request Form or Departmental Final Exam Request Form. These forms should be submitted online to the MechSE Graduate Programs Office at least one week prior to the exam. 

Preliminary Examination proposals should be 20 pages in length including introductory pages, figures, etc. It should include statement of proposed research, its objectives and significance; a brief review of previous work on related research; and a short discussion of tentative methods of analysis and/or experimentation. There are no specific format requirements for the proposal. 

Final Examination abstracts should be submitted as a double-spaced Microsoft Word document in Times New Roman, size 12 font. The research summary should be one paragraph long, submitted as a Microsoft word document in size 11, Calibri font.

PROCESS FOR REPORTING EXAM RESULTS

The process for reporting Prelim and Final exam results is as follows:

The Committee Chair should email mechse-grad@illinois.edu, cc’d to the committee members.  The email must include the following information:

  • For Preliminary Exams: 1) Date of the exam, 2) Result of the exam, 3) Names of committee members
  • For Final Exams: 1) Date of the exam, 2) Result of the exam, 3) Names of committee members, 4) How each committee member voted
  • For Thesis/Dissertation Approval Forms: 1) Approval of the document, 2) Names of committee members

The Graduate Programs Office will attach the result confirmation email to the PER/FER form, which should include the signature of the EO or DGS at the bottom. This departmental signature confirms the accuracy of the result, which aligns with our standard practice.

DOCTORAL EXAMINATION COMMITTEE REQUIREMENTS

  • Graduate College policy requires this committee shall have a minimum of 4 voting members, 3 of whom must be University of Illinois Graduate Faculty (i.e. they have an appointment with the Graduate College as teaching faculty who instruct a graduate course or courses.   MechSE policy states at least 1 of the 4 voting members must not be from the department of the candidate.  Committee members from outside the University of Illinois Urbana-Champaign are welcome but would serve in addition to the 3 University of Illinois Urbana-Champaign committee members.  If a member of the committee is non-UIUC faculty and will participate as a non-voting member, nothing additional is required.  If you desire a non-UIUC faculty member to serve as a voting committee member, a letter/email of justification from the advisor, stating what qualifies the person to be a voting member on the committee along with the person’s CV, must be attached to the exam request at the time of submission.
  • Three of the committee members must be listed as Graduate Faculty members and two must be tenured (Associate Professor or Professor).  The committee should include faculty members from more than one area of specialization.
  • The “Chair” must be a member of the Graduate Faculty from the candidate’s department and may also be the Director of Dissertation Research.  The chair is responsible for convening the committee, conducting the examination, and submitting the Certificate of Result to the department in which the student is enrolled.
  • A “Contingent Chair,” if designated, must be a member of the Graduate Faculty.  The Contingent Chair serves if the original chair is unable to serve for any reason.
  •  The Director of Dissertation Research is responsible for guiding/advising the student in their thesis research as part of an ongoing research project.  He/she may also discuss a tentative course of study or recommend a sequence of courses the student can take reflecting the interest of the student.
  • A Department Affiliate cannot serve as a “Chair” or a “Contingent Chair” of a Preliminary Examination or Final Examination Committee.  Only faculty members of the Department of Mechanical Science and Engineering may serve in that capacity.
