Dr. Becker is a board certified Medical Physicist. He received his PhD from University of Wisconsin-Madison in Medical Physics. Dr. Becker joined us, in 2014, from the NYU Langone Medical Center where he was a physicist in the Department of Radiation Oncology and scholar at the NYU Institute for Innovations in Medical Education.

Dr. Becker is an internationally known expert in the GammaPod (a stereotactic radiosurgery technique for the breast) and has traveled the world assisting new centers in the installation of their GammaPods.
