Biography
His focus is on orthopedic imaging including sports injuries, trauma, and musculoskeletal tumors. He has a special interest in innovative methods of teaching and forensic radiology.
Dr. Riley strives to develop teaching methods that go beyond the traditional lectures where trainees play a passive role. With his experience in serving as an expert witness in numerous civil cases, he has a special interest in educating trainees in medico-legal matters. He serves on the Medical Board of California as an expert reviewer, providing input on the standard of care for radiology.
As the radiology liason of Stanford Hospital's Sarcoma Tumor Board, he provides input on the care of patients with soft tissue, spine and bone tumors.
He is an active member of the Radiological Society of North America, the Society of Skeletal Radiology, and the American Roentgen Ray Society for which he is chair of the Scientific Program and Educational Exhibit Subcommittees. Dr. Riley serves on the American Board of Radiology Diagnostic Radiology Core MSK Committee as a test question writer.
As a manuscript reviewer for Skeletal Radiology, he reviews submitted articles and advises the editors of these journal on which submitted papers should be accepted for publication.
