Research Interests

My research focuses on understanding the biological mechanisms of

voluntary movement and deals equally with speech production and human

arm motion. I use mathematical models, robots and behavioral and

physiological techniques to assess motor function and the characteristics of

motor learning. The overall goals are to understand the interplay of

sensory and motor function and most recently, to understand how motor

learning and adaptation affects sensory function in speech and limb
