Mechanical Engineering (ME)

https://ceps.unh.edu/mechanical-engineering

Degrees Offered: Ph.D., M.Eng., M.S.

This program is offered in Durham.

The Department of Mechanical Engineering offers degree programs at both the master's and doctoral levels. The department offers studies leading to specialization in the following six concentrations: fluid and thermal science, mechanics, materials science, design and manufacturing, dynamic systems and control, and ocean engineering.

Admission Requirements

A bachelor of science degree in mechanical engineering is normally required for admission to the graduate program in mechanical engineering. Students from other disciplines may also be admitted to the program. However, in order to be properly prepared for graduate-level coursework, these students must have taken the equivalent of the UNH mechanical engineering undergraduate core courses listed below. Students who are deficient in three or fewer courses may be admitted to the department on a provisional basis. Students who are deficient in more than three courses must apply and enroll as an undergraduate student until they meet the core course requirement. It is department policy that engineering courses taken as part of an engineering technology program are generally not considered equivalent to any of the courses listed below. The decision on equivalence for any courses taken at an institution other than UNH is at the discretion of the Graduate Committee of the Mechanical Engineering Department.

Applicants must submit current scores (within five years) from the general test of the Graduate Record Examination (GRE).
