Master's Degree in Medical Engineering

Students are not normally admitted to work towards the M.S. degree. However, the M.S. degree may be awarded to a student along the way toward a Ph.D. degree, provided Institute and Option requirements are met. The Option requirements for the MS degree are the same as those for the Ph.D. degree except that the MS degree does not require research units, qualifying exam, candidacy exam, and thesis defense. In general, the degree is not conferred before the end of the first year of residence.

Three members must be Caltech professorial faculty affiliated with Medical Engineering. The fourth member may be a Caltech faculty member or an outside professional of similar standing. The committee must include the adviser, but another member of the committee must be selected as chair. The committee chair must be a Caltech professorial faculty member. This examination will be a test of the candidate's preparation and knowledge to conduct research in their specialized doctoral research area.

Thesis and Final Examination

The Ph.D. final thesis defense exam is conducted by a committee that is set up by the student and approved by the option representative. The committee should be made up of a minimum of 4 members and at least three of the committee members must be Caltech faculty. The committee must include the adviser, but another member of the committee must be selected as chair. The committee chair must be a Caltech Professorial faculty member.

This examination must be taken at least four weeks before the commencement at which the degree is to be granted. This thesis examination will be a defense of the doctoral thesis and a test of the candidate's knowledge in their specialized doctoral research area.

Med-EE Track Degree of Doctor of Philosophy

The track was established by Andrew and Peggy Cherng Department of Medical Engineering and the Department of Electrical Engineering at Caltech in the Fall 2022. The single degree to be shown on the diploma is "Ph.D. in Medical and Electrical Engineering".

Thesis and Final Examination

The Med-EE Ph.D. thesis must be related to both options. The final thesis defense exam is conducted by a committee that is set up by the student and approved by the option representative of the home department. The committee must be composed of 2 members from each option. The committee must include the advisor, but another member of the committee must be selected as chair. The committee chair must be a Caltech Professorial faculty member. This final examination will be given no less than two weeks after the doctoral thesis has been presented in final form, and before approval.

MedE Subject Minor

A subject minor is not required, but recommended, for the Ph.D. degree in medical engineering. However, credits from the subject minor cannot be double-counted for the core program. Students may choose their original engineering disciplines as their minor subjects. Students are not allowed to choose medical engineering as a subject minor.
