- Todd Royer investigates gait mechanics that contribute to risk factors associated with the development of knee osteoarthritis, and gait mechanics and energetics of human locomotion.
- Tom Kepple is developing custom Figure Skating Simulation Software program to be used in support of a project funded by United Sates Figure Skating. He also serves as the technical coordinator on the luminary site agreement between the College of Health Sciences and C-Motion, Inc. This work includes the development of new software and motion capture algorithms that support both the mission of the College of Health Sciences and C-Motion Inc. He is also developing software for improving and testing the performance of Motion Capture Systems. This includes software for locating force platforms, assessing the accurarcy of the force platform locations and testing the latency of the real-time Motion Analysis systems.
- Jim Richards focuses on three primary areas: 1) the development of new tools for measurement and analysis of human motion, 2) gait mechanics, and 3) biomechanical analysis of sport.
- Susan Hall is interested in clinical applications of biomechanics.
- Steven Stanhope’s research focus is in rehabilitation biomechanics, pediatric obesity, and community-based activity programs.
