Hi, I'm Jiachen Li (李嘉琛).  I am a third-year PhD student at UC Santa Barbara advised by William Wang

My current research interests broadly include Deep RL, and Embodied AI.

I am the Team Lead of Team GauchoAI. We won the 2nd place🥈 at the Alexa Prize SimBot Challenge! We made it to the final phase by ranking No.1 on the leaderboard!

My last project designed a closed-form solution to the policy improvement step for Offline RL.

I am open to collaboration on any research problem that will reveal new insights to the Machine Learning community.
