John Harvey

Biography

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.

Andrew Scott, M.S., DABR

Andrew

Biography

Mr. Scott earned his bachelors in physics at the University of South Carolina, where he developed a keen interest in particle interactions. As a member of the High Energy Physics Research Group, he investigated the character of high energy neutrino interactions with atomic nuclei.

Mr. Scott then earned his Masters in medical physics from Duke University. While at Duke, Mr. Scott worked at the Duke Radiation Dosimetry Laboratory investigating the occupational exposure to PET technologists and developing novel approaches to facility shielding design.

Mr. Scott entered active duty military service upon completion of his graduate studies. As an officer in the United States Air Force’s Biomedical Science Corps, he provided diagnostic imaging physics and radiation protection services to military medical facilities across the country. Mr. Scott is now delighted to put his skills to use as a member of the West Physics team.

Mr. Scott is originally from Savannah, Georgia.
