Biography

Steven K. Charles is currently an Associate Professor of Mechanical Engineering and a faculty member in BYU's Neuroscience Center. As a biomedical engineer, Steven investigates how humans control their movements, what goes wrong in movement disorders, and how to use technology to help patients with movement disorders. His interdisciplinary research lies at the intersection of engineering, neuroscience and rehabilitation. Before coming to BYU in 2010, Steven investigated the movement impairments of patients with cerebellar ataxia as a post-doctoral research fellow at Johns Hopkins University. While completing his Ph.D. in Mechanical and Medical Engineering from the Harvard-MIT Division of Health Sciences and Technology, Steven characterized human wrist movement behavior to set a baseline for robotic rehabilitation of wrist movements in stroke patients. Before his doctoral studies, he obtained an M.S. degree from MIT and a B.S. degree from Brigham Young University, both in Mechanical Engineering.
