Irina Vergalasova, PhD

Division of Radiation Physics

Dr. Vergalasova completed her undergraduate degree in Physics at Rutgers, The State University of New Jersey followed by her doctoral degree in Medical Physics at Duke University, after which she also completed her therapeutic physics residency at Duke University Medical Center. Dr. Vergalasova serves as the Director of Brachytherapy Physics, the Director of the Medical Physics Certificate Program and the Associate Director of the Medical Physics Residency Program. She also serves on a number of national AAPM and SDAMPP committees and is committed to giving back to the medical physics community as well as leaving a lasting impact on the education of future medical physicists. Dr. Vergalasova’s research interests include HDR brachytherapy, quantitative imaging, and stereotactic radiosurgery. Her educational research interests are focused on developing formalized professionalism training for medical physics residency programs. In her free time, Dr. Vergalasova enjoys traveling with family and friends, reading, and staying active.
