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 joined the University of Michigan as an Associate Professor in the Department of Electrical Engineering and Computer Science and the Robotics Institute in Fall 2019, and I became the Associate Director for Graduate Education of the Robotics Institute in Fall 2020. I joined the Department of Robotics upon its establishment in July 2022. Prior to joining U-M, I was an Assistant Professor in the Departments of Bioengineering and Mechanical Engineering at the University of Texas at Dallas. I was also 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

Note to Prospective Students

Funded positions are reserved for admitted PhD students based on availability of funding. Please do not email me requesting a RA position before you have applied to a U-M PhD program. You may notify me when you apply so I can look for your application, but please be patient because the admissions process takes time. Undergraduate or MS research opportunities may be available without financial support; feel free to send a resume and cover letter describing your interests. Unfortunately, I cannot sponsor visas for internships for international students. Note that I cannot reply to all inquiries, as I receive multiple per day.
