I am a medical oncologist who has clinical and research expertise in genitourinary medical oncology as well as clinical trials. My clinical practice is at Boston Medical Center and includes adult patients with cancers of the prostate, kidney, bladder, testicles and penis, as well as other solid cancers. My treatment expertise is in hormonal agents, chemotherapy, immunotherapy, targeted therapies, radioactive pharmaceuticals, bone targeted therapies, supportive and palliative care. I am also an educator in the Boston University School of Medicine and Boston Medical Center Hematology and Oncology Fellowship Program.
