Research description

My research explores changes in postural stability, manual control, and locomotion that occur as a function of age, development, and disease. I am particularly interested in how individuals across the life-span adapt their motor behaviors in varying contexts. Using a variety of analytical techniques (inspired from non-linear dynamics and chaos theory), my research has suggested that motor variability is a functional component of typical movement production. Specifically, nonrandom structured variations in generated movements aid the development of motor skills, increase balance control, and improve the ability of the motor system to successfully adapt and coordinate movements based on the context of the task and environment.

Currently, I am investigating decline that occurs in the integration between posture and other supra-postural behaviors in aged populations. This research is specifically examining ways to improve balance (reduce fall risk) in older individuals and individuals with Parkinson’s disease as they perform typical daily standing multi-task activities such as talking while producing precision hand movements.
