Research Summary

Major research interests are in the area of neuromechanics, particularly the restoration of movement by neuroprostheses employing functional neuromuscular stimulation. This research emphasizes the role of feedback and muscle and limb mechanical properties in the execution and regulation of movements. Current research projects include the control of wrist flexion/extension and elbow extension in patients with spinal cord injuries. Other projects involve the clinical implementation and evaluation of upper limb neuroprostheses, and the development of muscle models suitable for use in simulations with neuronal models.
