John Harvey, Ph.D., DABR, CHP

Director of National Technical Operations & Chief Medical/Health Physicist

John Harvey


Prior to joining West Physics, Dr. Harvey completed his Ph.D. at the University of Michigan in health physics. His research focused on the deployment of thermoluminescent radiation dosimeters in non-ideal conditions. He also participated in research into the computer-aided analysis of mammography and lung CT imaging. 

Dr. Harvey travels nationwide to perform imaging equipment quality assurance, and has served as Radiation Safety Officer for diverse clients, including a hospital network with locations throughout Georgia; an urban Level 1 Trauma Center; a rodent cancer research facility; a nationwide mobile nuclear medicine provider; and an international narcotics and explosives detector manufacturer.

Dr. Harvey enjoys teaching, and has developed and delivered content for eight semesters of university courses, including two while at West Physics. He has given talks at hospitals and conferences nationwide for audiences of technologists, physicians, radiology management, ancillary staff, and other physicists. Dr. Harvey serves as an instructor of Nuclear Engineering and Radiological Sciences at the University of Michigan, teaching Medical Imaging Physics. He currently serves as the Program Director of West Physics’ accredited residency program in diagnostic imaging and nuclear medicine physics. His daughter Ellie is his favorite student.

Dr. Harvey is originally from Plymouth, Michigan.
