I am a medical oncologist with a focus on genitourinary malignancies -- prostate, kidney, bladder, and testicular cancers. I am also a clinical and translational researcher focused on drug development and biomarker studies in prostate and kidney cancer. This research includes prognostic and predictive biomarkers, circulating tumor cell biology, and how cancer spreads (metastasis). I oversee multiple clinical trials of new therapies for patients ranging from new hormonal and chemotherapies to new immunotherapies, and molecularly targeted agents.
