lulu nustep

Dr. Ferris is a biomechanist whose research focuses on how the nervous system and musculoskeletal system interact to produce coordinated movement. Using a combination of techniques from engineering mechanics, neurophysiology, and non-linear dynamics, he studies both basic science and applied health issues. Some of the fundamental questions his research addresses include:

  • How flexible are the neural networks that control human locomotion?
  • Do the brain and spinal cord let the natural dynamics of the limbs determine movement patterns?
  • Can we use robotic exoskeletons to improve gait rehabilitation after spinal cord injury or stroke?

The common goal of his research is to discover general principles of locomotor control and apply them to improve human health.
