Electrical Engineering (EE)

Award of the Bachelor of Science degree may be followed by graduate study leading to the Master of Science degree in electrical engineering, and the more advanced degrees of Electrical Engineer or Doctor of Philosophy. Because admission to graduate studies in electrical engineering at Caltech is extremely competitive, the Admissions Committee attempts to select those applicants it judges both best qualified and best suited for the graduate program. Students are encouraged to submit the Graduate Record Examination (GRE) scores as part of the application package for the Ph.D. or M.S. degree programs in Electrical Engineering. Students who are unable to take the GRE in their home country will not be at a disadvantage due to the missing scores.

The Degree of Doctor of Philosophy offers two tracks: EE only and Medical and Electrical Engineering (Med-EE). The Med-EE track is offered jointly by both departments of Electrical Engineering and Medical Engineering (see MedE Section). The single degree to be shown on the diploma is “Ph.D. in Medical and Electrical Engineering.”

Normally, the master’s degree in electrical engineering is completed in one academic year. The principal criteria for evaluating applicants for the MSEE are the excellence of their preparation for the math- and physics-oriented nature of Caltech’s graduate courses, and the judgment of the Admissions Committee on their ability to successfully pursue and benefit from the course program. The Institute does not normally admit an applicant to the master’s degree in a field in which the applicant already has a master’s degree from another U.S. institution. Financial aid is seldom offered to those who intend to complete their graduate work with a master’s degree. A joint B.S./M.S. degree is not available in electrical engineering.

135 units (100 or above) are required as approved by the electrical engineering graduate student adviser. No more than 30 units of pass/fail grades may be counted toward this requirement. Units toward this are not transferable from other schools. At least 54 units of EE letter-graded courses (courses listed or cross-listed as EE) labeled 100 or above are required. EE 105 ac and EE 102, Electrical Engineering Seminar, are also required. Students are urged to consider including a humanities course in the remaining free electives.

Students who have been admitted to the M.S.-only program must reapply if they are interested in the Ph.D. program.

The engineer’s degree may be awarded in exceptional cases. The awarding of this degree requires fulfilling the Institute requirements for an engineer’s degree and receiving a recommendation for its awarding from the candidacy oral examination committee.

As a rule, applicants who wish to undertake research work leading to a degree of Doctor of Philosophy in electrical engineering are admitted initially only for the MSEE. They are, however, evaluated according to additional criteria, the most important of which is the applicant’s interestin and potential for research in one of the areas described below. The statement of purpose required as part of the application should clearly address this match. Considerable weight is also given to the opinions expressed in the applicant’s letters of recommendation.

During the Ph.D. applicant’s master’s degree year, evaluation continues. It is based in part on performance in courses and in part on a qualifying oral examination scheduled early in the second quarter. As the year progresses, the electrical engineering faculty get to know the student, and the student makes contact with the professor in their area of research interest. Upon acceptance into a research group, the student begins research work and defers receiving the master’s degree until formal admission into the Ph.D. program. If the Adviser is not an EE faculty member, the student should meet with the EE Option Representative and develop an oversight plan to monitor progress. Before the end of their third academic year of graduate study, the student takes the Ph.D. oral candidacy examination.

Financial aid available to a Ph.D. applicant includes teaching assistantships and fellowships. TA duties consist of grading papers or lab instruction but not classroom lecturing. A fellowship may be supplemented by a teaching assistantship, and either or both include a full tuition scholarship. Tuition scholarships alone are not available.

To be recommended for candidacy for the EE Ph.D. degree, the applicant must satisfy the following requirements (and pass the Ph.D. qualifying oral examination) no later than the end of the third academic year:

● Complete 18 units of research in their field of interest.

● Obtain approval of a course of study consisting of at least 135 units of advanced courses in electrical engineering or the related subjects approved by the Ph.D. adviser, with at least 54 units of letter-graded EE courses numbered 100 or above. No more than 30 units of pass/fail grades may be counted toward this requirement. The courses taken to satisfy the math requirement below and courses taken to fulfill the Master of Science degree requirement may be included to satisfy this requirement. Units toward this requirement are not transferable from other schools.

● Pass 27 units of mathematics courses, as approved by the student’s research adviser, with letter grade no lower than C.

● Pass an oral candidacy examination.

The Ph.D. qualifying oral exam and the final defense exam are conducted by committees that are set up by the student and approved by the option representative. Members of these Ph.D. committees also serve as second or backup mentors in cases where such additional advising and problem solving are appropriate.

The candidate is required to take a final oral examination covering the doctoral thesis and its significance in and relation to their major field. This final examination will be given no less than two weeks after the doctoral thesis has been presented in final form, and before its approval. This examination must be taken at least four weeks before the commencement at which the degree is to be granted. The committee must include the advisor, but another member of the committee must be selected as chair.

Periodic meetings between the advising faculty and the graduate student are an integral part of the Ph.D. program. These meetings should be at sufficiently frequent intervals, as determined by the student and adviser. Students are also encouraged to meet with other members of the Ph.D. committee, the option representative, the executive officer, or Caltech’s ombudsperson to discuss problems relating to satisfactory progress.

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

Admission to candidacy
To be recommended for candidacy for the Med-EE Ph.D. program, each student must do the following.

• Complete a minimum of 156 units of courses. The MedE requirement of 21 units of MedE courses plus the EE requirement of 135 units must be met. Cross-listed MedE/EE courses can be double counted.
  • MedE course requirements
    • Complete the three-term seminar sequence, MedE 100abc (1 unit), with a passing grade.
    • Complete MedE 101a (9 units).
    • Complete a 9-unit MedE course.
      • Biodevices: BE/EE/MedE 189ab (12 and 9 units), MedE 201 (9 units), MedE 202 (9 units), or MedE/EE 204 (9 units).
      • Biomechanics/Fluidics: MedE/BE/Ae 243 (9 units), ChE/BE/MedE 112 (9 units), or ChE 103b (9 units).
      • Biomedical Optics: MedE/EE 168abc (9 units each).
      • Medical Imaging: MedE/EE 268 (9 units).
    • All required courses must be taken for grades and passed with a grade no lower than C, except for those courses offered only for pass/fail.
  • EE course requirements
    • Complete 135 units total with no more than 30 units of pass/fail.
    • Complete 54 units of letter-graded EE courses numbered 100 or above towards the 135-unit requirement.
    • Complete 27 units of mathematics courses, with letter grade no lower than C. Many math-related courses can count towards the requirement after confirming with your advisor.
    • Complete 18 units of research in your field of interest directed by your advisor.
      
• Pass the oral qualifying and oral candidacy exams of the Electrical Engineering department for students having chosen Electrical Engineering as the home department. Please refer to the MedE Section for the reciprocal requirement.

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 its approval. 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.

A student majoring in another option at the Institute may elect a subject minor in electrical engineering. The student must obtain approval from the electrical engineering faculty of a course of study containing at least 45 units (over the 100 level) of advanced courses with an EE listing (excluding 291). At least 36 of these should be for letter grades no lower than C. Undergraduate first-year classes cannot be counted toward this.
