My research focuses on how different regions of the brain are involved in motor control and learning. I have developed a robotic device called KINARM that can both sense and perturb planar arm movements. One of my research labs examines neural activity in different brain regions of non-human primates during motor behavior. A second lab explores human motor performance and learning. A third lab located at St. Mary’s of the Lake Hospital is used to quantify sensorimotor impairments in stroke and other neurological disorders.
