Benjamin B. Williams

Benjamin B. Williams holds academic roles as Adjunct Professor of Engineering, Professor of Radiation Oncology and Applied Sciences, and Professor of Radiology at Dartmouth College’s Geisel School of Medicine. He specializes in biodosimetry, tissue oxygen measurement, and EPR (electron paramagnetic resonance) imaging techniques. His work focuses on clinical applications of EPR for radiation dosimetry, particularly in triage scenarios and radiation therapy monitoring.

• Education: BA in Physics from Kenyon College (1995); PhD in Medical Physics from University of Chicago (2003)
• Awards: Forbeck Scholar Award (2005), EPR International Conference Young Investigator Award (2005)

Research interests include developing physically-based biodosimetry methods using in vivo EPR of teeth, imaging tumor oxygenation for cancer therapy optimization, and advancing scintillation dosimetry for radiotherapy quality assurance. Over 20 years of contributions span medical physics, radiation oncology, and emergency response strategies for radiation incidents.

Professional activities include roles as Associate Director of the EPR Center for the Study of Viable Systems at Dartmouth (Biological Applications), membership in AAPM, ASTRO, and the International Association of Biological and EPR Radiation Dosimetry (IABERD). He serves on multiple scientific advisory boards and reviews for journals like Academic Radiology and Radiation and Environmental Biophysics.
