Dr. Timothy Deyer is the Chief Medical Information officer and Head of Musculoskeletal Interventional Services at East River Medical Imaging and Clinical Assistant Professor of Radiology at Weill Cornell Medical College, Cornell University. He is a board certified Musculoskeletal and Interventional Radiologist specializing in diagnostic musculoskeletal MRI and ultrasound and ultrasound guided procedures including musculoskeletal steroid and platelet rich plasma injections and soft tissue and bone biopsies. Dr. Deyer has written and co-authored numerous peer reviewed articles in several professional journals and as well as several book chapters. His research interests include application of Artificial Intelligence to radiology and radiologic evaluation of cartilage. He completed fellowships in interventional radiology at St. Luke’s-Roosevelt Medical Center and in Musculoskeletal Radiology at the Hospital for Special Surgery. He was a radiology resident at the Mount Sinai Medical Center, where he was Chief Resident in his final year. Dr. Timothy Deyer received his M.D. from the University of Michigan where he graduated in the top five of his class and was elected to the medical honor society Alpha Omega Alpha. He also completed an M.S.E. in Biomedical Engineering and B.S.E. in Mechanical Engineering at the University of Michigan.
