Benedick Fraass, PhD, FAAPM, FASTRO, FACR

Vice Chair for Research
Director, Medical Physics

Benedick Fraass, PhD, FAAPM, FASTRO, FACR is a member of the Department of Radiation Oncology at Cedars-Sinai. He serves as Vice Chair for Research and Director of Medical Physics.

Prior to joining Cedars-Sinai, Dr. Fraass was the Allen S. Lichter Professor of Radiation Oncology and Director of Radiation Physics in the Department of Radiation Oncology at the University of Michigan. Dr. Fraass earned his bachelor's in physics from Stanford University and his master's and doctorate in physics from the University of Illinois, Urbana-Champaign, where he did experimental low temperature solid state physics involving X-ray diffraction of solid helium crystals. He began his medical physics career in 1980 at the National Cancer Institute (NCI) at the National Institutes of Health in Bethesda Maryland, where he worked on radiation oncology physics and performed research in CT-based treatment planning, intraoperative radiation therapy and normal tissue tolerance.

Dr. Fraass joined Allen Lichter, MD, in founding the Department of Radiation Oncology at the University of Michigan in 1984. He served as the first Director of the Radiation Oncology Physics Division from 1984 until 2011. Dr. Fraass was instrumental in the treatment planning revolution in the 1980s and early 1990s, leading the development and first routine clinical use of 3-D treatment planning and 3-D conformal therapy. Since 1993, he has led an NCI-funded program project grant "Optimization of High Dose Conformal Therapyā€¯ which funds on-going clinical research in intensity modulated radiation therapy (IMRT), plan optimization, improved treatment delivery techniques, use of functional and multimodality imaging, as well as clinical studies in brain, head/neck, lung and liver cancer. He has published more than 190 journal articles on a range of issues from advanced treatment planning to quality assurance to clinical radiotherapy dose escalation studies.

Dr. Fraass is a fellow of the American Association of Physicists in Medicine (AAPM), the American Society of Radiation Oncology (ASTRO), and the American College of Radiology (ACR). He is currently Chair of the ASTRO Multidisciplinary Quality Assurance Subcommittee, Chair of the AAPM Research Committee, and member of the ASTRO Clinical Affairs and Quality Committee, AAPM Ad Hoc Safety Coordination Committee, Science Council, Therapy Physics Committee and Task Group 100 on Failure Modes and Effects Analysis for Intensity Modulated Radiation Therapy (IMRT).He currently leads the ASTRO effort to create a series of safety white papers on IMRT, IGRT, SBRT, HDR and peer review.
