I am a PhD student in the EECS department at MIT, advised by Russ Tedrake in the Robot Locomotion Group within CSAIL. I am interested in the planning and control of highly dynamic robots interacting with their environment, particularly in the challenges that arise from frictional contact and collisions. I also worked on the control, planning, and operations for the MIT DARPA Robotics Challenge Team.
