I am 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 have also worked on the control, planning, and operations for the MIT DARPA Robotics Challenge Team.

Much of the source code for my projects is openly available as part of the Drake toolbox or on my personal github.
