Zexi "Jesse" Zhang 张泽西

I am a CS Ph.D. student at Imperial College London and a member of the Safe Whole-body Intelligent Robotics Lab (SWIRL), advised by Prof. Stephen James. My research focuses on foundation models in robot learning. I also enjoy running RL on myself in the real world, where rewards are sparse and there is no reset button :)
