The long-term goal of the research in my laboratory is to understand how the human brain controls movement. In the attempt to answer this question, I have been studying a variety of human populations using neuropsychological, psychophysical, electrophysiological and biomechanical recordings as well as systems modeling (neural networks) and brain imaging techniques.
My lab has two primary research foci. The first focus is to understand the etiology and mechanisms of neurological diseases that affect the motor system. In the past, much of our work has centered around patients with dysfunctions of the cerebellum or the basal ganglia.
In addition, I have always have been interested in the development of motor function. Thus, my second research focus centers around how infants and children learn to control their bodies and how they acquire motor skills.
