Current Fellows in the Radiation Epidemiology Branch

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

  • Carolyn H. Brandt, B.S.

    Ms. Brandt, postbaccalaureate fellow in REB, is examining racial/ethnic disparities among breast cancer survivors. She is interested in further exploring health disparities, as well as relationships between tumor characteristics, treatment, and second cancer outcomes. Her mentors are Cody Ramin, Ph.D., and Amy Berrington de González, D. Phil.

  • 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.

  • Tae-Eun Kwon, Ph.D.

    Dr. Kwon, postdoctoral fellow in REB, is working on dose assessment for thyroid cancer patients and on dose recalculation for the U.S. Radiologic Technologists Cohort study, under the mentorship of Choonsik Lee, Ph.D., head of REB’s Dosimetry Unit.

  • 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.

  • Kishan Pithadia, B.S.

    Mr. Pithadia, NIH Medical Research Scholar Program Fellow in REB, is working on epidemiologic studies of second cancers related to therapeutic radiation exposure, under the mentorship of Lindsay Morton, Ph.D.

  • Cody Ramin, Ph.D.

    Dr. Ramin, research fellow in REB/ITEB, studies breast cancer etiology and survivorship. Her research primarily focuses on second cancer risk in breast cancer survivors and on the late effects of cancer treatment. Dr. Ramin has closely related interests in the hormonal etiology of breast cancer, breast cancer health disparities, and treatment-related cardiovascular disease. Her mentors are Amy Berrington, D.Phil, and Gretchen Gierach, Ph.D., M.P.H.

  • Thi Van Trinh Tran, Ph.D., M.P.H., B.Pharm.

    Dr. Tran, postdoctoral fellow in REB, is working to understand the influence of early life risk exposures and hormonal factors on thyroid cancer risk and the secondary effects of radioactive iodine for thyroid cancer, under the mentorship of Cari Kitahara, Ph.D.

  • Bryan S. Valcarcel, M.D.

    Dr. Valcarcel, postdoctoral fellow in REB, is working on curating a comprehensive database of cancer survivors who received hematopoietic cell transplantation during treatment. The data will be used to help identify the development of subsequent malignancies. His mentor is Lindsay Morton, Ph.D.

  • 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.
