Jason Ma

Hi there! I'm a final-year PhD student at UPenn GRASP Laboratory, where I am fortunate to be advised by Dinesh Jayaraman and Osbert Bastani. My research interests span robot learning, reinforcement learning, and foundation models for robotics. In particular, how to enable robots to learn from internet-scale multimodal data to unlock frontier and generalizable dexterous manipulation capabilities.

My research is supported by Apple Scholars in AI/ML PhD Fellowship. My work has received ICRA Best Paper Finalist as well as a best paper award at a CORL workshop. I am currently a student researcher at Google DeepMind; I have also interned at NVIDIA AI and Meta AI.
