Current Fellows in the Radiation Epidemiology Branch

Meet the fellows in the Radiation Epidemiology Branch (REB) and learn about their work.

  • Pragati Gole Advani, M.D., Dr.P.H., M.P.H.

    Dr. Advani, postdoctoral fellow in REB, conducts cancer survivorship research by investigating the etiology of treatment-related second cancers. Her mentor is Lindsay Morton, Ph.D.

  • Aryana Arsham, Ph.D.

    Dr. Arsham, postdoctoral fellow in BB and REB, focuses on predicting dose rates using machine learning methods for the assessment of cancer risk as well as Age-Period-Cohort modelling for addressing disparities in cancer incidence amongst different groups. Her mentors are Mark Little, D.Phil., and Philip Rosenberg, Ph.D.

  • David Borrego, Ph.D.

    Dr. David Borrego, research fellow and independent research scholar, focuses his research focuses on improving our understanding of ionizing radiation and associated health risks, and the development of models to clarify how ionizing radiation, like medical x-rays from radiography and fluoroscopy, deposits energy in the tissues of the human body.

  • Konstantin Chizhov, Ph.D.

    Dr. Chizhov, postdoctoral fellow in REB, conducts radiation dosimetry for studies of the Chernobyl accident and atomic bomb survivors. His mentors are Choonsik Lee, Ph.D., and Elizabeth K. Cahoon, Ph.D.

  • Keith Griffin, M.S.

    Mr. Griffin, predoctoral fellow in REB, is helping to establish the computational dosimetry methods needed for future epidemiological studies of proton therapy on a patient-specific basis. His mentor is Choonsik Lee, Ph.D.

  • Kaitlyn Hardell, Ph.D., M.P.H.

    Dr. Hardell, postdoctoral fellow in REB, studies the relationships between genetics, cancer treatment, and second cancer risks among cancer survivors. Her mentor is Lindsay Morton, Ph.D.

  • Jim Mai, M.D., M.P.H., Ph.D.

    Dr. Mai, postdoctoral fellow in REB, works on multidisciplinary studies of UVR exposure, photosensitizing medications, oncoviruses infection/activation, and cancer risk among SEER participants, U.S. radiologic technologists, and Medicare recipients. His mentor is Elizabeth Cahoon, Ph.D.

  • Elisa Pasqual, M.D., Ph.D.

    Dr. Pasqual, postdoctoral fellow in REB, studies secondary effects in thyroid cancer survivors treated with radioactive iodine. She also works on thyroid cancer etiology, in particular, the role of obesity as a risk factor. Her mentor is Cari Kitahara, Ph.D.

  • Cody Ramin, Ph.D.

    Dr. Ramin, an NCI Cancer Prevention Fellowship Program research fellow in REB/ITEB, studies breast cancer etiology and the role of cancer therapy on second cancer risk and cardiovascular disease among breast cancer survivors. Her mentors are Amy Berrington, D.Phil, and Gretchen Gierach, Ph.D., M.P.H., ITEB.

  • Jacqueline B. Vo., Ph.D., R.N., M.P.H.

    Dr. Vo, postdoctoral fellow in REB, examines the impact of cancer treatment on cardiovascular morbidity and mortality among breast cancer survivors and characterizes trends in cardiovascular disease mortality among adult-onset cancer survivors in the U.S. Her mentor is Amy Berrington, D. Phil.

  • Yeon Soo Yeom, Ph.D.

    Dr. Yeom, postdoctoral fellow in REB, conducts dosimetry studies for radiation epidemiology focusing on dose reconstruction for proton therapy patients. His mentor is Choonsik Lee, Ph.D.
