I am a cancer epidemiologist with more than ten years of research experience investigating the etiology of cancer risk as well as studying lifestyle and genetic factors associated with cancer progression. I have expertise in prostate cancer research, and am Principal Investigator of several funded grants across various aspects of prostate cancer etiology, molecular subclassification and prognostication. I am a co-investigator of the Physicians’ Health Study and co-Project Leader of the Prostate Cancer project of the Health Professionals Follow-up Study. A major research focus is on tumor biomarkers, and I co-lead the Harvard prostate cancer patho-epidemiology team. My research includes immunohistochemical evaluation and a large-scale genome wide expression profiling study within large cohorts of men with prostate cancer from the United States and Sweden.
