PhD in Mechanical Engineering

The PhD program in Mechanical Engineering provides both post-bachelor’s and post-master’s applicants the opportunity for study in a broad range of areas, many of which overlap with other disciplines within the College and the University. ME faculty members boast international reputations and provide students with opportunities for research in:

  • Acoustics and Vibrations
  • Biomechanics
  • Computational Science and Engineering
  • Dynamics, Robotics, Systems and Controls
  • Thermofluid Sciences, Energy and Sustainability
  • Materials
  • MEMS and Nanotechnology

Course Requirements

Post-Bachelor’s Students

  • must complete all departmental requirements for the Master of Science degree
  • are required to complete a minimum of 64 credits applicable to their degree (a minimum of 24 credits must be structured courses and a minimum of 16 credits of research/dissertation is required).

Post-Master’s Students

  • develop a curriculum in consultation with their faculty advisor
  • are required to complete 32 credits applicable to their degree, all of which must be at the 500 level or higher
  • are required to complete a minimum of 8 credits of research/dissertation coursework.

Residency Requirement

Each student must satisfy a residency requirement of a minimum of two consecutive regular semesters of full-time graduate study at Boston University. Full-time study in this context means full-time commitment to the discipline as determined by the Associate Dean for Research and Graduate Programs.

All PhD students are required to fulfill the math requirement no later than the end of their fourth academic semester. The list of courses will be reviewed periodically by the ME Graduate Committee.

Dissertation Prospectus Defense

  • Within one year of becoming a candidate, the student is expected to present an oral dissertation proposal to the prospective Dissertation Committee and obtain approval for the written dissertation prospectus.

Dissertation

  • A PhD candidate is expected to prepare and carry out an independent and original research project in partial fulfillment of the dissertation requirement.
  • The Dissertation Committee must consist of College of Engineering (tenured or tenure-earning) faculty.

Final Oral Examination

  • Students shall present themselves for a final oral examination in which they must defend their dissertation as a worthy contribution to knowledge in their field and demonstrate mastery of their field of specialization as related to the dissertation.
  • The Examining Committee is composed of at least five members, of which two must be (tenured or tenure-earning) faculty from the student’s academic department/division.

Time Limit

  • Both the post-bachelor’s and post-master’s programs must be completed within five years of the individual’s acceptance into PhD candidacy.

Advising

  • Candidates for the PhD degrees are required to have a member of the graduate faculty in the department/division of their major field as an advisor.
