Research Interests:

My broad research area is human movement control, with a focus on movement variability.  Although variability is a robust characteristic of our movements, it increases with aging and certain neurological diseases.  The exacerbation in movement variability has serious functional implications. My research attempts to: 1) better understand the neural mechanisms of movement variability; 2) characterize the consequences of exacerbated movement variability in activities of daily living; 3) develop innovative rehabilitation tools to reduce deleterious movement variability.
