Brent Yi

Hello! I'm a final-year PhD student at UC Berkeley, where I'm advised by Prof. Angjoo Kanazawa and Yi Ma. My work is supported by the NSF Fellowship.

I'm currently an intern at Amazon FAR. Before the PhD, I worked with Jeannette Bohg during my MS at Stanford, and Pieter Abbeel during my BA at UC Berkeley.
