Current Fellows in the Hormonal and Reproductive Epidemiology Branch

Meet the current fellows in the Hormonal and Reproductive Epidemiology Branch and learn about research training opportunities.

Armen Ghazarian, M.P.H. - Predoctoral Fellow

Armen Ghazarian

Armen Ghazarian, M.P.H., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a predoctoral fellow in September 2012 as part of the collaborative doctoral training partnership in cancer epidemiology with  George Washington University. Prior to joining HREB, he worked in NCI’s Division of Cancer Control and Population Sciences (DCCPS) as an environmental epidemiology CRTA fellow. Mr. Ghazarian attended the University of Maryland, College Park where he received a B.S. in biological sciences in 2008 followed by an M.P.H. in epidemiology in 2011. His master’s thesis focused on socioeconomic disparities of esophageal adenocarcinoma using data from NCI’s Surveillance, Epidemiology, and End Results (SEER) Program. His research interests include cancer and environmental epidemiology, gene and environment interactions, endocrine disruptors, social determinants of health, and hormonally-related cancers including prostate and testicular. Mr. Ghazarian is working with Katherine A. McGlynn, Ph.D., M.P.H., Deputy Chief of HREB, and Britton Trabert, Ph.D., M.S., Investigator, HREB, on studies of male cancers.

Scott Kelly, M.S. - Predoctoral Fellow

Scott Kelly

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.

Maeve Mullooly, Ph.D., M.P.H. - Postdoctoral Fellow

Mauve Mullooly

Maeve Mullooly, Ph.D., M.P.H., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as an NCI Cancer Prevention Fellow. Dr. Mullooly received her B.Sc. in pharmacology from University College Dublin (UCD) in Ireland, followed by her Ph.D. in translational medicine from St. Vincent’s University Hospital and UCD’s School of Medicine and Medical Science. During her doctoral studies, she investigated proteases as novel therapeutic targets for breast cancer with a focus on triple negative breast cancer. Her project formed part of the strategic multicenter and multidisciplinary research cluster “Molecular Therapeutics for Cancer Ireland” funded by Science Foundation Ireland. Dr. Mullooly recently completed her M.P.H. at UCD’s School of Public Health, Physiotherapy and Population Science. During her fellowship in HREB, Dr. Mullooly is focusing on molecular epidemiologic studies of breast density and breast cancer, working primarily with HREB investigator Gretchen Gierach, Ph.D.,M.P.H., Investigator, HREB.

Hannah Oh, Sc.D., M.P.H. – Postdoctoral Fellow

Hannah Oh, Sc.D., M.P.H., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a postdoctoral fellow in December 2014. Prior to joining the branch, Dr. Oh received a B.A. in molecular and cell biology from the University of California, Berkeley, an M.P.H. in global health from Emory University (2010), and an Sc.D. in epidemiology and nutrition from Harvard University (2014). Her doctoral dissertation focused on lifestyle factors (physical activity, body fatness, diet) and hormones in relation to breast cancer. In HREB, she is working with Gretchen Gierach, Ph.D., M.P.H., investigator, HREB, on projects related to mammographic density and terminal duct lobular unit (TDLU) involution in normal breast tissue to identify markers that may improve risk assessment and early detection of breast cancer. She is also working with Britton Trabert, Ph.D., M.S., investigator, HREB, on projects related to sex steroid hormone metabolites (e.g., estrogen metabolites) and studies of endometrial and ovarian cancer.

Jessica Petrick, Ph.D., M.P.H. – Postdoctoral Fellow

Jessica Petrick

Jessica L. Petrick, Ph.D., M.P.H., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a postdoctoral fellow in June 2014. She obtained a B.A. in public health studies and medical anthropology, and an M.P.H. (2008) in epidemiology and health policy from Case Western Reserve University. Dr. Petrick received her Ph.D. in epidemiology from the University of North Carolina at Chapel Hill in 2014. For her doctoral dissertation, Dr. Petrick examined the intake of dietary flavonoids in relation to the incidence of Barrett esophagus and esophageal and gastric cancer, and to survival among esophageal and gastric cancer cases. Her Ph.D. mentor was Dr. Marilie Gammon. In HREB, Dr. Petrick works with Katherine A. McGlynn, Ph.D., Deputy Chief of HREB, on liver cancer studies assessing gender-specific effects of risk factors such as coffee consumption, diabetes, obesity and steroid hormone levels, and with Michael B. Cook, Ph.D., Investigator, HREB on the effects of adiposity on esophageal adenocarcinoma risk.

Baiyu Yang, Ph.D. – Postdoctoral Fellow

Baiyu Yang, Ph.D., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a postdoctoral fellow in July 2015. Prior to joining the branch, Dr. Yang obtained her Bachelor of Medicine (B.Med.) in preventive medicine from Fudan University, China (2010), and her Ph.D. in epidemiology from Emory University (2015). For her doctoral dissertation research, she investigated the role of calcium consumption in relation to biomarkers of risk for colorectal cancer and other chronic diseases, survival from colorectal cancer, and risk for all-cause and cause-specific mortality. She also worked with the American Cancer Society to explore other risk factors associated with colorectal cancer survival. In HREB, Dr. Yang works with Katherine A. McGlynn, Ph.D., Deputy Chief and senior investigator, HREB, applying her clinical and epidemiologic training to the study of the gut-liver axis, including the role of inflammation, obesity, diabetes, and medication use in the development of liver cancer.

Cindy Zhou, Ph.D. - Postdoctoral Fellow

Cindy Zhou, Ph.D., joined the Hormonal and Reproductive Epidemiology Branch (HREB) as a predoctoral fellow in October 2012. In 2010, she received her Bachelor of Medicine (B.Med.) in preventive medicine from the West China Center of Medical Sciences, Sichuan University, China. For her B.Med. research project, Dr. Zhou examined socioeconomic and behavioral factors in breast cancer screening among women in southwest China. In 2008 – 2009, she served as a resident in the West China Hospital, Sichuan, China, rotating through the Departments of Oncology, Rehabilitation, Gerontology and General Medicine. In the summer of 2009, Dr. Zhou was an intern with the Center for Disease Control and Prevention in Zigong, China, working on the HIV/AIDS Sentinel Surveillance program. In 2011, she worked on several projects related to prostate cancer with Dr. Ann Hsing, formerly a senior investigator in the Infections and Immunoepidemiology Branch. For her doctoral dissertation, Dr. Zhou worked with HREB investigator Michael B. Cook, Ph.D., Investigator, HREB, on research pertaining to the etiology of prostate cancer. She recently received her Ph.D. from the Department of Epidemiology and Biostatistics at George Washington University School of Public Health and Health Services.
