Background

Dr. Jonathan Sackett's journey began with physics research at CERN in Geneva, where a conversation about the first hospital-based proton treatment center inspired his pursuit of an interdisciplinary career bridging physics and medicine. During medical school at Loma Linda University, he was selected for the competitive NIH Medical Research Scholars Program, where he developed AI techniques for prostate cancer imaging at the National Cancer Institute. He recently completed the ASTRO-Varian Radiation Oncology Research Training fellowship, focusing on AI applications in radiotherapy planning. His research centers on developing artificial intelligence solutions to improve cancer imaging and radiation treatment planning, with particular expertise in genitourinary and central nervous system malignancies.
