Professor and Director of Physics Division



Randall K. Ten Haken, Ph.D., is the Director of the Physics Division within the Department of Radiation Oncology. He is a tenured Professor and serves as an Associate Departmental Chair. He is a Fellow of the American Association of Physicists in Medicine (FAAPM), a Fellow of the Institute of Physics (FInstP), a Fellow of the American Society for Radiation Oncology (FASTRO), and a Fellow of the American College of Radiology (FACR). He is also the Principal Investigator/Program Director of a long-standing program project grant related to the Optimization of High Dose Conformal Therapy. The overall goal of that program project is to improve the effectiveness of radiation therapy for cancer patients by individualizing therapy beyond simple anatomy. Specifically, we seek to use both anatomical and physiological information acquired during treatment to re-optimize therapy based on the individual patient’s treatment history and response.

Over the past quarter century, Randy Ten Haken has directed the efforts of numerous graduate students, postdoctoral fellows, and medical residents during their research years. He has published numerous articles on geometric and dosimetric uncertainties in patient treatments. He has developed novel iso-toxicity based treatment approaches for radiotherapy dose escalation and published extensively on assessing and modeling treatment outcomes. He recently served as co-guest editor for a special supplement of the International Journal of Radiation Oncology Biology and Physics dedicated to the Quantitative Analyses of Normal Tissue Effects in the Clinic (QUANTEC). He couples this background and expertise with investigational leadership and collaborative skills to help combine the physics and clinical outcomes research aspects of many complex projects. In collaboration with his colleagues within the department as well as others throughout the University of Michigan, his research currently focuses primarily on the investigation of patient-based adaptive techniques and outcomes assessments using physiological imaging for use in optimization of treatment techniques. This investigation of “response-based” optimization of adaptive therapy is one of the core focuses of the Physics Division.
