Research Interests
  • Developing a system that combines electrical stimulation of paralyzed muscles with a mechanical brace to restore walking to individuals with paraplegia.
  • Exploring the fundamental characteristics of tiny hydraulic systems and their application to powered exoskeletons for orthotics and human power amplification.
  • Developing a tiny internal combustion engine and compressor for supplying compressed air to portable, wearable pneumatic systems.
  • Researching the mechanical properties of human muscle including developing new research and clinical diagnostic instrumentation to quickly and easily measure muscle function.
  • Assessing performance characteristics of tools and devices used in surgical procedures.
  • Exploring new ways to educate engineers, including low-cost take-home lab kits.
