David J. Reinkensmeyer David Reinkensmeyer is Professor in the Departments of Mechanical and Aerospace Engineering, Anatomy and Neurobiology, Biomedical Engineering, and Physical Medicine and Rehabilitation at the University of California Irvine. His research interests are in neuromuscular control, motor learning, robotics, and rehabilitation. A major goal of his research is to develop physically interacting, robotic and mechatronic devices to help the nervous system recover the ability to control movement of the arm, hand, and leg after neurologic injuries such as stroke and spinal cord injury. He is also investigating the computational mechanisms of human motor learning in order to provide a rational basis for designing movement training devices. He is Editor-in-Chief of the Journal of Neuroengineering and Rehabilitation. His laboratory has helped develop a variety of robotic devices for manipulating and measuring movement in humans and rodents, including two devices that have been successfully commercialized as Flint Rehabilitation's MusicGlove and as Hocoma's ArmeoSpring. Volker DietzVolker Dietz, neurologist, is Professor emeritus and former Director of Spinal Cord Injury Center and Chair of Paraplegiology, University of Zürich, Balgrist Hospital, Switzerland. His research is focused on neuroplasticity, neurorehabilitation technology and regeneration. He retired in 2009, having worked at the University of Zürich since 1992. Presently he is Senior Research Professor at the University Hospital Balgrist. Previously he had an educational grant at the National Institute for Neurology, Queen Square, London. Afterwards he held a position at the University of Freiburg and was guest professor at the Miami project to cure paralysis. He has been on the editorial board of the several journals of neurology and neurosciences. He has been awarded various honors and awards including the Schellenberg Prize for outstanding research in paraplegia in 2012.
