Dr. Descovich is a Professor in the UCSF Department of Radiation Oncology and she is certified by the American Board of Radiology. She received her Ph.D. in Nuclear Physics from the University of Liverpool, UK, where she developed gamma ray tracking detectors to study the behavior of radioactive nuclei. She specializes in the physics of stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT), and has been the lead physicist of the robotic radiosurgery program since the installation of the CyberKnife at the Helen Diller Family Comprehensive Cancer Center in 2010. Her current research is focused on robotic SBRT, with an emphasis on motion management ant target tracking.
