Staff Scientist

NCI Shady Grove | 7E538



Dr. Gibson has a B.S. in nutrition sciences from Cornell University, an M.S. in molecular biology from Lehigh University, and a Ph.D. in epidemiology from Yale University. In DCEG, he completed a predoctoral fellowship in the Nutrition Epidemiology Branch, where his dissertation work focused on the role of folate and one-carbon metabolism on cancer risk. After receiving his Ph.D. in 2010, Dr. Gibson was selected for the NCI Cancer Prevention Fellowship Program and completed a postdoctoral fellowship in the Radiation Epidemiology Branch. In 2014, he joined the faculty at St. Jude Children’s Research Hospital as an assistant member, where he developed a research program elucidating risk factors for adverse late effects among survivors of childhood cancer. While at St. Jude, Dr. Gibson also served as the project director for the Childhood Cancer Survivor Study. In January 2020, he joined REB as a staff scientist.

Dr. Gibson has received several awards for his work, including an NCI Director’s Career Development Innovation award, a Cancer Prevention Fellowship Achievement award, an AACR Scholar-in-Training award, and the James B.

Research Interests

Dr. Gibson has broad expertise and interest in elucidating risk factors for subsequent cancers among cancer survivors, with a focus on the role of cancer treatments and genetic factors. He is currently supporting the Pediatric Proton and Photon Therapy  Comparison Cohort study and other studies of childhood cancer survivors, including investigations of genetic susceptibility to treatment-related second cancers.
