PhD in Mechanical Engineering
The Department of Mechanical Science and Engineering offers a world-class program leading to the PhD in Mechanical Engineering. The program offers tremendous flexibility in course selection with a rigorous qualifying exam based on upper-level undergraduate course work.
The PhD in Mechanical Engineering can be done in conjunction with the MS degree or alone (aka Direct PhD). Most students joining the department enter the PhD program in Stage 1, during which they 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

Students planning to take the new format of the qualifying exam must complete the prerequisite requirement (details below) prior to registering for the exam.
A student pursuing the PhD alone (Direct PhD) is Stage 1 until the prerequisite for the qualifying exam has been completed.
Stage 2: Qualifying Exam, PhD Coursework, Preliminary Examination
The Department requires graduate students to successfully complete a Qualifying Examination to formally enter the Ph.D. program.
There are two formats for ME qualifying examination, the “old format” and the “new format.” The new format will be available from Fall 2016. Current graduate students who have not taken their qualifying exam yet can opt for either the old format or the new format. Graduate students joining the department beginning Spring 2017 can take their qualifying exam in the new format only. Current students (enrolled during Fall 2016 or earlier) who are taking the exam during AY 16-17 are required to let the Graduate Programs Office know of their choice of the qualifying exam format by August 30, 2016. Once the choice is made, it cannot be changed.
Available as an option to students whose first term of enrollment is Fall 2016 or earlier. The last offering of the old format will be August 2018.
Students are required to take the exam within one calendar year of completion of their MS degree. You can download sample examinations should you want them. Also, please download the exam scheduling guidelines and both the research examination proposal cover sheet and PhD qualifying examination registration form to schedule your exam.
New format (starting Fall 2016)
ME PhD Qualifying Examination (beginning Fall 2016)
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 article 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.
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 Ph.D. Qualifying Exam Registration Request form to the Graduate Programs Office (166 MEB). Exams schedules will be set based on committee availability, and not earlier than 3 weeks from the time of the request approval.
- Advisors will email the names of three suggested committee members and two 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 two suggested articles from the advisor and the timeline in which the exam needs to be scheduled.
- The committee members will respond to the graduate programs office with their availability and the Graduate Programs Supervisor will facilitate the exam scheduling.
- Notice of the exam date and time and the selected article will be sent to the student two weeks prior to the exam date.
Oral Examination Committee: A committee of two faculty members appointed by the Associate Head for each examinee will administer the hour-long oral exam. The committee may not have the student’s thesis advisor.
Journal article: The student will be examined on a published, peer-reviewed archival journal article related to student’s research. The student’s adviser may suggest a list of papers to the examining committee. The committee may choose the paper from the list, or it can choose the paper outside the list. These articles are expected to be comprehensive representing a seminal work in the field. The article will be provided to the student two weeks ahead of the exam. In addition to reading the article, the student is expected to review the related literature.
Grading: The student must present the material from the article in 30 minutes, and answer committee’s questions in the remaining 30 mins. 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.

Students enrolled in a course that conflicts with ME 590 or TAM 500 still need to register for ME 590/TAM 500 and are required to attend alternate seminars.
To complete seminar registration with a conflict:
1. Request a registration override by contacting the Undergraduate Programs Office at mechse-ug-adviseillinois [dot] edu. Include your name, UIN, and the course you are enrolled in that is in conflict with the seminar.
2. You will receive an email when the override is entered.
3. You must register for ME 590 after the override is entered.
To receive credit for alternate seminars:
1. Alternate seminars include ME 591 MIG, ME 591 BIG, TAM 539, and other seminars in Engineering, Math, or Physics.
2. Download the Attendance Verification Form and have it signed by the seminar host (not the speaker), and return it to GPO no later than 5 business days after the date of the seminar. If an attendance verification form is not received, you will not receive credit for attending.
