Timothy R. Rebbeck, Ph.D.
Professor of Epidemiology

RebbeckDr. Rebbeck is Professor of Epidemiology at the Dana Farber Cancer Institute and the Harvard T.H. Chan School of Public Health. He leads molecular epidemiology studies of cancer etiology, outcomes, health disparities, and global health. His work has led to an understanding of the genetic and environmental causes of cancer risk, outcomes, and disparities. He currently leads international cancer consortia that study risk and outcomes of 1) cancer in BRCA1/BRCA2 mutation carriers, and 2) prostate cancer in men of African descent in North America, the Caribbean, and Africa.




Dr. Evan Busch
Postdoctoral Fellow
Evan BuschEvan received his PhD in Epidemiology in May 2015 from the University of North Carolina at Chapel Hill, where he worked on the use of markers of epithelial-mesenchymal transition to improve the accuracy of cancer staging.  He joined the De Vivo Lab as a postdoctoral fellow in Summer 2015.  His research will focus on refining molecular subtypes of endometrial cancer.  He is interested in molecular and genetic cancer epidemiology as well as epidemiologic methods.




Dr. Lori Chibnik
Assistant Professor

Lori ChibnikDr. Lori Chibnik, PhD, MPH, is the newest PGSG faculty member. She is an Assistant Professor of Neurology at HMS and Brigham and Women’s Hospital, with a secondary appointment in HSPH-Epidemiology. Her research focuses on genetics and epigenetics of Alzheimer’s disease, cognitive decline, and multiple sclerosis; and longitudinal data analysis and risk prediction. She and Peter Kraft co-teach EPI 215: Advanced Topics in Case-Control & Cohort Studies (aka “Big data for Epidemiologists”) in the Fall semester. Dr. Chibnik also developed and leads an interactive biostatistics course at the KwaZulu-Natal Research Institute for Tuberculosis and HIV in Durban, South Africa.



Xuanyao Liu
Postdoctoral Fellow

XuanyaoXuanyao obtained her Ph.D. from National University of Singapore and joined the Price Lab in December 2014. She worked on population genetics and developed statistical methods for detecting positive natural selection signals in both human and parasite genome. Her current research focuses on partitioning heritability across functional categories and inferring genetic component of population differences in phenotypes.
