Professional Summary

Dr. Andrew Erwin is an Assistant Professor in Mechanical Engineering at the University of Cincinnati. Prior to joining UC, he was a postdoc at the University of Southern California and the Jet Propulsion Laboratory. His degrees are in mechanical engineering with a PhD from Rice University and a BS from the University of Massachusetts Amherst.

Research and Teaching Interests
​Physical human-robot interaction
Rehabilitation robotics
Bio-inspired robotics
Haptic interfaces
Motor learning
System dynamics and controls

With a perspective in robotics, my research focuses on understanding how forces and movements are executed in healthy function; how function might be restored, assisted, or substituted after injury; and how human movement can inspire the design and control of robotic devices.
