Board Certifications

Radiation Oncology

I am a board-certified radiation oncologist and scientist who specializes in treating breast cancerprostate cancer, and primary and metastatic brain tumors. I have expertise in using advanced radiation therapy techniques, such as intensity-modulated radiation therapyimage-guided radiation therapystereotactic body radiation therapy, and stereotactic radiosurgery. I see patients at Memorial Hospital in Manhattan and MSK Bergen in New Jersey. 

My research is focused on molecular and biomarker-driven clinical trials and translational studies that aim to make the newest discoveries available for our patients. Our group has developed several treatments that define how breast cancer is treated around the world. Our main goal is to enhance the precision with which radiation is delivered by using the latest molecular techniques to select patients appropriately, and then applying the latest advances in radiation technology to accurately and conformally target the tumor while sparing nearby normal tissue.

As part of my clinical and scientific work, I serve on several national and international committees including the American Society of Clinical Oncology, the American Society for Radiation Oncology, and NRG Oncology, among others.

When I first meet with patients, my goal is to ensure they are informed and feel empowered.
