Research Interests

Neuromuscular determinants of motor function (movement) in health and disease. Current projects address three main topics:

  1. Aging - identifying the adaptations responsible for the declines in sensorimotor function with advancing age.
  2. Motor units - characterizing the modulation of the activation signal sent from the nervous system to muscle and its influence on muscle function.
  3. Multiple sclerosis - evaluating therapeutic strategies that can reduce the burden of multiple sclerosis by restoring walking ability and reducing fatigue
