I received the B.S. degree (2006) in electrical engineering and computer sciences from the University of California, Berkeley and the M.S. (2007) and Ph.D. (2010) degrees in electrical and computer engineering from the University of Illinois at Urbana-Champaign. I will join the University of Michigan as an Associate Professor in the Department of Electrical Engineering and Computer Science and the Robotics Institute in Fall 2019. I joined the Departments of Bioengineering and Mechanical Engineering at the University of Texas at Dallas as an Assistant Professor in June 2013 with an adjunct appointment at the UT Southwestern Medical Center. Prior to joining UTD, I was a Research Scientist at the Rehabilitation Institute of Chicago and a Postdoctoral Fellow at Northwestern University. I am the Director of the Locomotor Control Systems Laboratory, which conducts research on the control mechanisms of bipedal locomotion with applications to wearable and autonomous robots.   Curriculum Vitae

Personal Interests

Outside of the office, I can sometimes be found on the ice playing in pickup hockey games. I also enjoy watching Cal football and Ducks hockey whenever they are televised locally. Most of my free time is now dedicated to my wife Kristin and a mutt named Oskee. 

Note to Prospective Students:
I am moving to the University of Michigan and am no longer accepting new students/interns at UT Dallas. Prospective or current UM students may e-mail a cover letter and resume/CV as PDF attachments. Incomplete applications will not be considered.
