Joshua Schiff, MD

Dr. Joshua P. Schiff is an Assistant Professor of Clinical Radiation Oncology at the Keck School of Medicine. He joined the faculty in the fall of 2024. His clinical practice is currently primarily at the Norris Comprehensive Cancer Center.

He grew up in Los Angeles in the San Fernando Valley, and graduated from the University of California, Santa Barbara with a bachelor’s degree in Biopsychology. He earned his medical doctorate degree at the Tulane University School of Medicine, where he was inducted into the Alpha Omega Alpha Honor Medical Society. He completed his residency at the Washington University School of Medicine in St. Louis, where he was chief resident.

Dr. Schiff specializes in the treatment of a variety of cancer types using advanced radiotherapy delivery methods. He has extensive experience with modern treatment techniques including intensity-modulated radiation therapy, volumetric-modulated arc therapy, stereotactic radiosurgery, stereotactic body radiotherapy, and motion management techniques. He has obtained funding for and opened multiple clinical trials with a focus on the implementation of new technology to improve treatment outcomes for patients, having previously focused on online adaptive radiotherapy, and now focusing on biology-guided radiotherapy. His work has resulted in numerous publications, presentations at national meetings, and awards, including the Roentgen Resident/Fellow Research award from the Radiological Society of North America.
