Ruth H. Walker, MB, ChB, PhD, obtained her medical degree from the University of Edinburgh, Scotland, and went on to complete a PhD in basal ganglia neuroanatomy at the University of Edinburgh and MIT. Following a neurology residency at New York University School of Medicine, she returned to the basal ganglia for a fellowship in Movement Disorders at Mount Sinai School of Medicine. She is currently Director of the Movement Disorders Clinic at the James J. Peters Veterans' Affairs Medical Center, and is also a member of the Department of Neurology at Mount Sinai School of Medicine.

Dr. Walker's research focuses on the functional neuroanatomy of the basal ganglia and clinicopathologic correlations of neurogenetic disorders. Her particular clinical interests are the hyperkinetic disorders, especially the rarer inherited causes of chorea.
