Research Center

Dr. Witztum is an Assistant Professor at the UCSF Department of Radiation Oncology. He received his DPhil in Oncology from the University of Oxford, UK and completed his residency at UCSF. His doctoral work was on incorporating spatial dose distribution information in toxicity models. His clinical interests are in data-driven insights, toxicity/outcome modeling, and clinical automation. He explores these themes through programming and machine learning techniques.
