Research Description: 

My research investigates the kinematics and kinetics of human movement, using experimental data techniques such as 3D motion capture, force measurement and electromyography in conjunction with computer muscle models. A main focus of my research is to examine how muscular properties influence movement patterns.  To that end I use musculoskeletal and forward dynamics models to study optimal movement patterns and task-specific muscle synergism. Current projects include the effect of age-related changes in muscular properties on balance, coordination changes while learning to direct external forces, and limitations on maximal sprinting speed.
