Steven Jax, PhD
Bio

Dr. Jax strongly believes that improving rehabilitation can best be accomplished by applying basic-science theories to clinical populations.

His PhD in basic sensorimotor processing (Penn State, 2005), combined with his postdoctoral training (University of Pennsylvania/MRRI, 2005-2007), uniquely positions him to understand and improve neurorehabilitation. 

His research has been funded by the NIH, the Albert Einstein Society, and the Pennsylvania Department of Health.

 

Research Interests
  • Influence of cognitive and perceptual systems on movement production
  • Perceptual-motor disorders
  • Upper-extremity rehabilitation
