Overview

What the Master of Science in Mechanical Engineering is

Graduate study here is meant to take you well past the level of a strong undergraduate program. The core courses set that level, and you then work with faculty scholars on advanced topics across mechanical engineering and mechanics. Along the way you become familiar with how research is supported, funded and presented.

Graduate students also share the department with undergraduates, and that mix keeps teaching methods and course material improving, a benefit the department counts as part of its mission alongside research and service to industry and society.

A 30-credit degree, typically 1.5–2 years of full-time study, delivered on campus, hybrid or fully online.

Research areas

Research on machines, materials and energy

Across all three research areas, the department’s faculty and students take on large, complex problems: making machines and autonomous systems dependable, designing structures that are safer and more efficient, and meeting energy and health needs through better use of fluids and heat. Master’s students can build on this work through their department and free electives.

Machines that sense, decide and act reliably

Mechanical Systems

Machines are taking on more complex work, from automated production to systems that operate on their own, and they have to behave predictably. Researchers in this area develop the control methods and autonomous systems that make machines dependable, including control of the plasma used in nuclear fusion devices.

Focus topics: Control Systems, Robotics and Autonomous Systems, Nuclear-Fusion Plasma Control.

Structures and materials that are safer and more efficient

Solid Mechanics

Every part, from a medical implant to a load-bearing frame, has to carry force without failing. Work in this area studies how solids deform, resist and generate stress, from designing structures that make the best use of material to the biological tissues and molecular mechanisms behind that behavior.

Focus topics: Mechanics for Optimized Design, Biomechanics, Molecular Mechanics and Fundamental Mechanisms of Stress Generation.

Using energy and fluids more effectively

Thermo-Fluids

The movement of air, water and blood and the transfer of heat sit behind energy systems, vehicles and medical technology. This area studies flows from their fundamental behavior to bio-inspired design and biomedical applications, and applies that understanding to renewable energy.

Focus topics: Bio-Inspired Flows, Biomedical Flows, Renewable Energy, Fundamental Flows.

Curriculum

What you study

The degree requires 30 graduate credits: a required mathematics course, two core courses, and then electives that you shape around your interests, with room to take courses in other departments.

  • Required mathematics course, 3 credits. Everyone takes Mathematical Methods in Engineering I (ME 452).
  • Core courses, 6 credits. Choose two from Advanced Manufacturing Science, Numerical Methods in Mechanical Engineering, Heat and Mass Transfer, Advanced Fluid Mechanics, Linear Systems and Control, Mathematical Methods in Engineering II, Introduction to Elasticity, and Analytical Methods in Dynamics and Vibrations.
  • Mechanical engineering and mechanics electives, 9 credits. Three courses in ME and MECH at the 300 and 400 level. ME 460, ME 490 and ME 499 do not count here, and only one course in this group may be at the 300 level.
  • Free electives, 12 credits. Four courses at the 300 and 400 level in ME and MECH or in another department. Up to two courses from another department may be at the 200 level.
  • Grades. You need a B- or better in at least eighteen credits of your program and in all 300 courses in the major field. No course graded below C- counts toward the degree.
  • Courses that do not count. Courses with an ESLP subject code, undergraduate-only 300-level courses such as Apprentice Teaching, Directed Study, Senior Thesis and Seminar Credit, and doctoral-only 400-level courses cannot be applied to the degree.
