George F. Wittenberg, MD, PhD

Professor of Neurology, Bioengineering, Physical Medicine & Rehabilitation

Title(s)

  • Director, Laboratory for Research on Arm Function and Therapy (RAFT)
  • Medical Director, Rehab Neural Engineering Labs
  • Associate Director/Research, Technology Enhancing Cognition & Health, Geriatrics Research Education & Clinical Center, VAPHS

Biographical Sketch

Dr. Wittenberg received training at Harvard, UC San Diego, Washington U., St. Louis, the National Institutes of Health, and KU Leuven. His clinical and research interests are in neurorehabilitation, stroke, cerebral palsy and movement disorders. He uses transcranial magnetic stimulation, functional imaging, and rehabilitation robotics to study recovery of motor function.

He has a tenured appointment as Professor in the Department of Neurology and is a Neurologist/Researcher in the Veterans Affairs Pittsburgh Healthcare System. He has secondary appointments in Bioengineering and Physical Medicine and Rehabilitation. He is Director of the Laboratory for Research on Arm Function and Therapy (RAFT), one of the Rehab Neural Engineering Labs, which has a multidisciplinary faculty of 8. He arrived in Pittsburgh in 2018 as the outgoing Director of the VA Maryland Exercise and Robotics Center of Excellence. He is now one of the investigators in the joint Pitt/VA Human Engineering Research Laboratory, and the VA TECH-GRECC.

Dr. Wittenberg is a Fellow of the American Society of Neurorehabilitation and Board Certified in Neurology and Brain Injury Medicine. He is an Associate Editor of Neurorehabilitation and Neural Repair and on the Pitt Active Mobility Committee, chairs the Neurology Grand Rounds Committee, and is on the local StrokeNet and national Stroke Recovery & Rehabilitation advisory panels.
