Paul A. Ellison is a medical physicist whose interests utilize the principles and techniques of nuclear and radiochemistry to address challenges in nuclear medicine. As an undergraduate student, he performed research modeling the biokinetic pathways of folding proteins. Dr. Ellison pursued his doctorate at the Department of Chemistry, University of California–Berkeley, specializing in nuclear chemistry. As a postdoctoral researcher, he joined the field of medical physics at the University of Wisconsin, becoming heavily involved in medical isotope production and radiochemistry. Since 2020, Dr. Ellison has been an assistant professor in the Department of Medical Physics at the University of Wisconsin School of Medicine and Public Health. His work focuses on developing small molecules radiolabeled with matched positron-emitting and Auger-electron-emitting therapeutic radionuclides for the planning and execution of targeted radionuclide therapy for cancer.
