Dr. Feldman received his medical degree from the University of Massachusetts Medical School and completed his residency in Urology and fellowship in Urologic Oncology at Massachusetts General Hospital (MGH). He currently serves as Associate Professor of Surgery at Harvard Medical School and as Program Director of the Combined Harvard Medical School Urologic Oncology Fellowship. In his clinical practice, he focuses on the treatment of urothelial cancer, prostate cancer, kidney cancer and other genitourinary malignancies. 

‌Dr. Feldman's research focuses on advancing both translational and clinical understanding of prostate, bladder and kidney cancers. His work in novel proteomic biomarker discovery led to a Prostate Cancer Foundation Young Investigator Award and subsequently a Physician Research Training Award by the Department of Defense. He has since received several federally funded, foundation and industry sponsored research grants for his work in biomarker development, metabolomics and imaging in genitourinary malignancies. He has published over 100 peer-reviewed manuscripts, and has served on multiple regional, national and international grant review, scientific program and steering committees. In addition to his work in translational research, he has worked diligently to build multiple clinical outcomes databases at MGH in prostate cancer, urothelial cancer and renal cell carcinoma.
