PhD Program

The Medical Physics Program leading to a PhD degree through the Jacobs School of Medicine and Biomedical Sciences.

The goal of the PhD Program in Medical Physics is to provide a sound academic foundation and practical experience for those planning to pursue a career in research, teaching or clinical medical physics in either of the subspecialty areas of medical imaging physics, therapeutic radiation physics or nuclear medicine physics.

Graduates are prepared for careers in these subspecialties or the continuation of their education in a postgraduate or residency program. The program comprises both academic and practical training components with the practical training taking place in affiliated hospitals.

The Medical Physics program is accredited by the Commission on Accreditation of Medical Physics Educational Programs, CAMPEP.

The Medical Physics group comprises faculty in multiple UB and Roswell Park Comprehensive Cancer Center departments, postdoctoral staff, graduate student assistants and undergraduate students, with additional contributions from bioengineering and clinical and allied faculty as well as technical and administrative staff. The Medical Physics program faculty conduct research, teach and practice clinical medical physics in affiliated hospitals.

Program Objectives

The PhD Program is interdisciplinary in outlook, and strives to draw together medical physics interests from throughout the academic community.

Accordingly, collaborative relationships are maintained with a number of laboratories outside the department. Notable among these associations are the Radiation Oncology and Biophysics departments at Roswell Park Comprehensive Cancer Center.

On campus, long-standing links exist with the departments of Radiology, Nuclear Medicine, Neurosurgery, Biomedical Engineering, Electrical and Computer Engineering, Mechanical and Aerospace Engineering. A number of faculty members in these departments hold joint appointments in the Department of Radiology.

Consequently, a broad spectrum of medical physics expertise and research opportunities are available to students in the Medical Physics program.

Structure of the Program

The instruction and research in the Medical Physics Program can be broadly categorized into three subspecialty areas: diagnostic and interventional imaging, radiation therapy and nuclear medicine physics. Additionally, experiences in clinical medical physics are offered. Current imaging research programs involve new detector development for rapid sequence, high resolution radiography, fluoroscopy and angiography, region of interest and micro computed tomography, system characterization and optimization, single photon counting and dosimetry.

Research into the development of high resolution systems for image guided interventions and the development of interventional devices such as specialized stents for blood flow modification and treatment of cerebral aneurysms as well as 3D printed vascular and other models are also actively being pursued.

Two modern angiography suites dedicated to imaging physics and pre-clinical research are available in the new UB Clinical and Translational Science Institute. Image analysis and image processing involving guidance and interventional neuro and cardio vascular procedures and 3D imaging are other active projects. Magnetic resonance imaging projects using clinical and experimental high field dedicated animal systems are available at the CTRC and Roswell Park.

A full range of external beam and brachytherapy projects are actively being pursued at Roswell Park where four linear accelerators and a Gamma-knife facility are available.

Nuclear medicine physics faculty members are active in emission tomography imaging technology research. State-of-the-art emission tomographic imaging systems are available for research and teaching, including several clinical positron emission tomography (PET) and PET/CT systems, a dedicated small animal PET (microPET), clinical SPECT (single photon emission computed tomography) systems, and radiopharmaceutical laboratories.

Multi-modality research projects are also encouraged and may be fostered by the complementary interests of participating faculty. The program combines faculty and resources from both UB and Roswell Park.

Individual student programs are tailored to the student’s needs and interest, and to ensure broad experience in the major areas of the medical physics. A graduate student in the Medical Physics Program enjoys considerable freedom in the development of dissertation research and in the choice of his/her major professor.

PhD Program Requirements

Credit Hours

A total of at least 72 credit hours are required for the PhD degree. Of this total, at least 28 credit hours must be earned in formal didactic coursework (including letter-graded Independent Study), as well as 4 credit hours in Seminar plus at least 2 credit hours Medical Physics Practicum; excluded are Research, Thesis Guidance, Supervised Teaching, and (unless receiving a priori approval under special circumstances) pass/fail Independent Study courses. Where appropriate, didactic course credits may be transferred from other graduate programs.

Required Courses

The following courses, where graded, must be successfully completed with the achievement of a grade of B or better.

Required of all students in the Medical Physics Program:

Substitution of a more advanced course(s) is only upon approval by the adviser and program director.

An additional 3-credit elective is required for PhD students and at least 3 additional credits from at least one of the following selected specialties is required for all students:

Medical Imaging Physics

Therapeutic Radiation Physics

Nuclear Medicine Physics

Other Electives

The following courses may be used as elective upon approval by the adviser:

Qualified students may petition for a waiver of the requirement for any specific course upon the basis of the completion of an equivalent course with a grade of B or higher.

Students may be subject to a comprehensive examination once completing all core medical physics courses.


Doctoral students are required to register for credit in Seminar for at least 4 semesters. In addition, attendance at the Medical Physics Program seminar series is expected of all students throughout the duration of their graduate programs. During this period, each student is expected to present at least one seminar.


Advancement to candidacy for the PhD degree requires the completion of all programmatic course requirements, and satisfaction of the preliminary examination requirements.

Preliminary Examination

The preliminary examination for the PhD consists of the preparation of an independent written research proposal and an oral defense. The proposal topic is chosen by the student. It may address a research topic that overlaps with the thesis project. The proposal is normally prepared in the form of a research grant application; as an alternative, however, a paper authored by the student and accepted for publication in an appropriate journal or international conference proceeding may be substituted. In either case, the choice of topic should be approved beforehand by the director of graduate studies of the Medical Physics Program. The research proposal and its oral defense should be completed by the beginning of the student's fifth semester in residence.

The research proposal should present compelling evidence of the scientific soundness and feasibility of the proposed research. Upon completion, the proposal is submitted to the director of the Medical Physics Program. If found to be appropriate with respect to topic, format, and technical production, the proposal will then be submitted to a faculty review committee, consisting of at least three faculty in the Medical Physics Program, for scientific evaluation. Should the review committee find the written proposal unacceptable, it will be returned to the student with comments for revision. 

Following approval of the written document, an oral defense of the proposal before the same review committee will be scheduled. Questions posed by the reviewers, while directed primarily toward the proposal, will also explore the student's mastery of basic concepts of medical physics.

Should the oral presentation be found to be inadequate, the committee will inform the student of the areas of weakness. A second defense will be scheduled after a period of time appropriate to the deficit. Failure of the second defense is grounds for dismissal from the program. Failure to successfully prepare and defend a proposal, within the limitations of these policies and time schedule, may be grounds for dismissal from the graduate program.

Dissertation Research, Preparation, and Review

The dissertation research is conducted by the graduate student under the tutelage of the Dissertation Committee consisting of the major professor and at least three additional university faculty, two of whom are members of the program’s graduate faculty; all committee members should hold the rank of assistant professor or above. The Dissertation Committee critically monitors and supervises preparation of the dissertation and will meet at least semi-annually with the student during the course of the dissertation project. These meetings will serve to provide a progress report to the committee. The oral defense of the dissertation is scheduled after the candidate’s Dissertation Committee and the Program have approved the dissertation. The research represented by the dissertation is presented in a seminar prior to the formal oral defense before the Committee.

Financial Assistance

Doctoral students, admitted to candidacy after passing the qualifying examination, normally receive financial support in the form of a graduate/research assistantship or part-time job.

Highly qualified underrepresented minority candidates may be eligible for assistance through the Arthur A. Schomburg Fellowship.

Federal grants and loans are available by filing the FAFSA application.
