The MS degree requires 30 hours of credit, six of which are obtained by the preparation of the required thesis. This course work must include the graduate-level Physics courses in experimental physics, quantum mechanics, classical electrodynamics, the physics of sensors, and the technical seminar. Supporting work must be chosen from engineering, chemistry, or geological sciences. Work done for a Master's degree may also be used as part of the Ph.D program, but earning a Master's degree does not extend any of the deadlines specified for the doctoral program. A Master's degree is not required for a Ph.D. degree, and most students proceed directly to the doctorate.
