Will Liang

I'm a computer science student at the University of Pennsylvania. I'm working on robot learning in the GRASP Laboratory, where I'm fortunate to be mentored by Jason Ma and advised by Dinesh Jayaraman, Osbert Bastani, and Jianbo Shi. My interests are multimodal representations, large language models, and reinforcement learning for intelligent, robust embodied agents.

Previously, I've interned at Anduril Industries and and Hudson River Trading. I've also dabbled in traditional art and game development.
