I am a molecular epidemiologist with a background as a board-certified internal medicine physician. My main research interest is how potentially modifiable exposures cause solid tumors through genomic heterogeneity and influence cancer progression. I am passionate about combining state-of-the-art genomics and well-defined observational studies in order to inform primary prevention, risk stratification, and biomarker-guided treatment. My methodologic and teaching interests include the application of epidemiologic methods to biomarker and clinical studies.

As a Research Associate with Dr. Philip Kantoff’s group, I lead highly interdisciplinary and collaborative research projects across epidemiology, genomics, pathology, bioinformatics, and clinical medicine, with additional experimental validation in cell culture systems. I am the principal investigator of a 2017 Prostate Cancer Foundation Young Investigator Award and a 2018 Department of Defense Early-Investigator Research Award.

As an example of my work on genomic heterogeneity of prostate cancer, I showed that tumors that are very active in synthesizing cholesterol are more likely to metastasize. These results support that cholesterol-lowering statin medications could indeed improve patients’ prognosis, and cholesterol synthesis activity may be a suitable predictive biomarker for clinical trials. In another research lead, I developed methodology to measure the extent of aneuploidy—aberrant numbers of chromosomes—in the tumor transcriptome. We showed that aneuploidy is a strong risk factor for progression to lethal disease, suggesting a potential to better understand the etiology of lethal tumors and to identify therapeutic targets in prostate cancer and beyond.
