University of Washington
Dr. Shuman received his undergraduate degree from Yale and medical degree from the State University of New York. After completing a residency in Diagnostic Radiology at the University of Vermont in Burlington in 1979, Dr. Shuman went on to a two-year fellowship in Ultrasound and Computed Tomography at the University of Washington. Dr. Shuman continued as faculty at UW, raising to the rank of Professor in the Departments of Radiology, Oncology, and Radiation Oncology in 1988. While at the University of Washington, Dr. Shuman served as the Director of CT (1982 – 1990) and MR (1983 – 1990). Subsequently, he moved to become Director of Computed Tomography, Ultrasound, and MR at the University of Vermont (1992 – 1995) while continuing to hold Clinical Professorships at the University of Washington and Seattle University. In 1995, Dr. Shuman became the Director of CT/MR/US at Evergreen Hospital Medical Center in Kirkland, WA and eventually Medical Director of Diagnostic Imaging. He also rose to CEO of Radia Medical Imaging, the largest private practice Radiology group in the western US. However, in 2003 Dr. Shuman returned to the University of Washington to become Professor, Medical Director of Radiology at UW Medical Center, and Vice Chair of Radiology. He subsequently served as Interim Chairman of the Department of Radiology from 2016 – 2019, after which he was promoted to Professor Emeritus.
Outside the University of Washington, Dr. Shuman is the Past President of the Society of Computed Body Tomography/MR (SCBT/MR), now the Society for Advanced Body Imaging and has served on the Radiology Education Alliance of the ACR as well as numerous committees for multiple societies. His CV lists 155 peer reviewed publications. His research interests center on dual energy CT in body imaging, cardiac CT, and iterative/AI image reconstruction techniques.
