About Department

Department of Mechanical Engineering Ph.D. program has been approved in the Fall of 2008, and accepted students in Spring 2009. With a young and energetic staff, an emphasis on co-operation with the industry and several R & D and consultancy projects, the department is striving for excellence in both undergraduate and graduate education in Mechanical Engineering. The Ph.D. program aims at educating researchers who may serve in leading industrial companies by conducting high quality research, or who may be employed as faculty members in high ranked national and international universities.
Mechanical Engineering Ph.D. program accepts students with an undergraduate or graduate degree in Mechanical, Chemical, Industrial, Aerospace, Mechatronics, Control, Metallurgical or Materials Engineering, or Naval Architecture, or with an undergraduate degree in other areas of engineering with a minor in Mechanical Engineering. Candidates for the Ph.D. program are given an interview and are required to demonstrate their English proficiency. Depending on the undergraduate degree, candidate may be admitted first to an Academic Preparation Program.
Mechanical Engineering Ph.D. program consists of 21 credits of course work (which is usually equivalent to seven courses), a qualifying exam, thesis proposal and thesis work. Courses to be completed are chosen among the masters of doctoral level courses by the approval of the academic advisor. The list of courses can be accessed by “Academics > Ph.D. > Course Descriptions” link within this website. Other courses offered by the Institute of Science and Engineering can also be taken by consulting with the advisor.
If it is deemed necessary, the student takes a total of 18 credits of undergraduate coursework towards the Academic Preparation Program, which must be completed within two semesters. The student must receive a minimum CGPA of 2.50 out of 4.00 and a minimum grade of CC in each course taken in the Academic Preparation Program.
