Research and Interests

Research Interests

Professor Iverson is an internationally-recognized clinician scientist in three areas: (1) Evidence-Based Neurocognitive Assessment in Psychiatry and Neurology, (2) Sport-Related Concussion, and (3) Mild Traumatic Brain Injury. He has published more than 260 empirical articles, reviews, and book chapters. Some of his publications are listed below.

          Mild Traumatic Brain Injury: Dr. Iverson has a longstanding research interest in outcome from mild traumatic brain injury. He is involved in ongoing clinical research with injured civilians, active duty military personnel, and veterans. He is currently collaborating on several studies relating to outcome from mild traumatic brain injury with researchers from the US Army, Defense and Veterans Brain Injury Center, and the US Department of Veterans Affairs. He was a founding member of the Traumatic Brain Injury Subcommittee of the Defense Health Board, a civilian advisory board to the United States Secretary of Defense
