Doctoral Electrical Engineering Degree
The PhD degree requires 90 credit hours of graduate study, 60 of these being beyond a master’s degree.
All PhD students must take and pass 16 credits of ECE graduate-level coursework. At least two ECE graduate-level courses from their concentration area and at least one ECE graduate-level course from each of the other two concentration areas. These four ECE courses must be taken during the first year of study.
The Comprehensive Examination, to be completed by the end of the third semester of study, is required for continuation in the PhD program. Students may petition to extend the time for completing these requirements. Part-time students and those with a non-ECE background may need additional time.
If a PhD student wishes to pursue a MS in electrical engineering, two additional courses will be required to complete a total of 24 course credits toward the 30 required for the MS (non-thesis) degree. At least 16 of these course credits must be in ECE courses. The Comprehensive Examination will complete the MS Final Exam requirement for the MS degree.
All graduate students matriculated for the PhD degree are required to perform a certain amount of teaching assistance as part of their education. Teaching experience deepens and enriches a student’s understanding of the discipline and provides invaluable professional training and is, therefore, considered to be a vital component of any PhD program. The ECE department requires two semesters of TA experience.
For more information about program requirements see the Electrical and Computer Engineering Department Bulletin or talk to an advisor. For information about financial aid and applying to the PhD program, visit the apply to Rochester page.
All doctoral students must pass a PhD qualifying examination and submit a written PhD thesis proposal in their third to fourth year of full-time graduate study.
Students who pass the PhD qualifying examination will get thesis research assistance from the Faculty Thesis Advisory Committee. The student's research advisor serves as chair. The committee meets with the student at least once each year.
PhD concentrations and research areas are broken up into three overarching topics:
- Signal Processing, Music Acoustics, and Communications
- Integrated Electronics and Computer Engineering
- Nanoscale Electronics, Photonics, and Acoustics
Students will take two graduate-level classes in their chosen concentration area and at least one graduate-level course from each of the other two concentration areas. The specific courses will be selected by each individual student and their research advisor.
Biomedical Ultrasound and Biomedical Engineering
High-frequency sound (ultrasound) is used in many areas of medicine to obtain images of soft organs in the body. High-intensity ultrasound is used to destroy kidney and gallstones without surgery (lithotripsy).
Students in this program will conduct scientific investigations that focus on the interactions of ultrasonic energy with biological materials ranging from heart and liver tissues, to bones and gallstones. Students may also conduct research on the applications of ultrasonic contrast-producing agents similar to radiological contrast and tracer techniques.
The results from these efforts are used to improve or extend clinical applications of ultrasonic techniques, both in diagnosing diseases of the heart and liver, and in therapeutic users such as lithotripsy. This work is also used to set standards for exposure of patients during examination and to improve the application of high-intensity sound for therapy.

VLSI/IC Microelectronics and Computer Design
Students in this program work in a variety of VLSI/IC microelectronics and computer design research areas. Some of the current research being conducted here at Rochester includes:
- Research in VLSI and CAE to address topics in integrated circuit design methodologies and automation.

- Applying VLSI design and analysis techniques to develop ultrafast superconducting digital integrated circuits.
- Designing and analyzing high performance VLSI-based digital and analog integrated circuits and their systems. Specifically, speed, area, and power dissipation tradeoffs are investigated in terms of application-specific constraints and their fundamental circuit level limitations.
In a new and ever-changing landscape of electronics needs, there has been a strong focus to work with deeply scaled nanoelectronic transistors and to go beyond conventional Si-based transistors entirely. New technologies such as spintronics, 2D electronics, phase-change electronics, neuromorphic electronics, superconducting electronics and topological electronics are becoming more important in defining what the next 50 years of electronics looks like from the device level up.
Students in this program work in a variety of next generation nanoelectronic device research areas. Some of the current research being conducted here at Rochester includes:
