Scott Kelly, M.S. - Predoctoral Fellow

Scott Kelly, M.S. joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a predoctoral fellow in November 2013 as part of the collaborative doctoral training partnership in cancer epidemiology with George Washington University. Mr. Kelly received his M.S. in biostatistics and epidemiology from Georgetown University in 2009. His master’s thesis focused on risk factors of congenital cardiovascular malformations for infants born in the mid-Atlantic region of the United States. Prior to joining the branch, he worked as a biostatistician and data manager within the Cancer Prevention and Control program of the Lombardi Comprehensive Cancer Center at Georgetown University. His research interests include genetic, hormonal, lifestyle and environmental factors that modify prostate cancer risk, progression, and survival outcomes. For his doctoral dissertation, Mr. Kelly is working with Michael B. Cook, Ph.D., Investigator, HREB, on research pertaining to the role of hormonal and genetic mechanisms in the pathogenesis of prostate cancer, as well as novel analyses of incidence trends and survival rates.
