Research interests
Eye movements, Vestibular and balance disorders, Cerebellar ataxia, Traumatic brain injury

Dr. Walker is an Associate Professor of Neurology at Case Western Reserve University. He is also a Staff Neurologist and Director of the Daroff-Dell’Osso Ocular Motility Laboratory at the Louis Stokes Cleveland VA Medical Center. Dr. Walker is also Co-Director of the newly designated National VA Parkinson’s Disease Consortium Center due to his tremendous clinical research and clinical efforts related to Parkinson’s Disease and movement disorders. This designation will ensure accessibility and continuity of specialized care for Veterans afflicted by parkinsonism, regardless of locality.

Dr. Walker’s research uses systems neuroscience approaches to investigate how the brain controls eye movements and to understand why vision and balance are impaired in people with neurological disorders such as ataxia, multiple sclerosis, and traumatic brain injury. Current work focuses on the role of the gravity and motion sensing reflexes of the vestibular system in these conditions.

Charts illustrating range of sway in veteran with mTBI and without mTBI

From a project for diagnosis of balance impairments following mild traumatic brain injury (TBI). In the figure above, the left panel shows the range of sway in a subject without mTBI and the right panel the sway in a veteran with mTBI and imbalance, after a forward perturbation.
