I am an Assistant Professor in the Robotics Institute and School of Computer Science at Carnegie Mellon University.

I lead the Interactive and Trustworthy Robotics Lab (Intent Lab). We study how to enable robots to safely interact with the "open world". We broadly draw upon methods from optimal control, dynamic game theory, uncertainty quantification, and deep learning.

I obtained my Ph.D. in electrical engineering & computer science at UC Berkeley with Anca Dragan and Claire Tomlin. Previously, I was also a postdoctoral scholar with Jitendra Malik and worked at NVIDIA in the Autonomous Vehicle Research Group.
