About the Program

The PhD degree offered by the Mechanical Engineering and Mechanics (MEM) Department offers courses often associated with one or more areas of specialization: design and manufacturing, mechanics, systems and control, and thermal and fluid sciences. The mechanical engineering field is rapidly changing due to ongoing advances in modern science and technology. Effective mechanical engineers must possess expertise in mechanical engineering core subjects, interdisciplinary skills, teamwork skills, as well as entrepreneurial and managerial abilities. The degree programs are designed so students can learn the state-of-the-art knowledge now, and have the foundation to acquire new knowledge as they develop in future.     

The PhD degree program is offered for full-time students only and is a research intensive program. The research areas include, but are not limited to, bio-engineering, energy systems, high performance materials, nanotechnology, plasma science and engineering and robotics. 

For more information, please visit the PhD in Mechanical Engineering webpage.

Admission Requirements

Applicants must meet the graduate requirements for admission to Drexel University. Students holding a bachelor's degree in a science or engineering discipline other than mechanical engineering are advised to take several undergraduate courses as preparation for graduate studies. Though these courses are not counted toward the required credits for the degree, they also must be listed in the student's plan of study. Outstanding students with a GPA of at least 3.5 in their master’s program will be considered for admission to the program leading to the Doctor of Philosophy degree in Mechanical Engineering and Mechanics.

PhD Program Requirements

Candidacy Requirements

The PhD candidacy exam consists of two parts: a course examination part and an oral examination part.

  • For the course examination part, an earned grade of A- or higher on 2 courses from the MEM Selected Core Course list is required. These 2 courses should be from a two-course sequence (or any two of a three-course sequence, such as MEM 611 / MEM 612 / MEM 613) in (1) Mechanics, (2) Thermal and Fluid Sciences, and/or (3) Dynamic Systems and Controls Cores. Note that grades earned in (4) Design and Manufacturing Courses cannot be the basis for fulfilling this requirement. However, completion of MEM 619, MEM 687, MEM 678 and MEM 679 may be counted towards the core courses.
  • For the oral examination part, the research component examination consists of a written report and an oral presentation. The Candidacy Committee selects three or more research papers in the student’s declared research area for student to conduct a critical review and identify areas for future research and development. In three weeks after the papers have been assigned to the student, the student submits a written report not exceeding 15 single-spaced pages, excluding references. One week after the written report is submitted the student makes an oral presentation. The presentation is followed by questions by the Committee. The goals of the questions are to evaluate the student’s knowledge in the scientific fields related to the research area, including related background and fundamental material, and to assess the student’s ability to integrate information germane to success in research.

The candidacy may be completed at any time following matriculation but must be attempted no later than the end of the second academic year, for full-time students, and successfully completed not later than the end of the third academic year, for full-time students. The composition of the Candidacy Committee should be selected with the approval of the Program Manager of Graduate Studies. Special circumstances should also be discussed with the Program Manager.
