Short Bio

I’m now a researcher at Machine Learning Group, Microsoft Research (Asia) under Li Zhao’s group. My current research interests include reinforcement learning and foundation models for embodied AI. I was also responsible for the project of Vision-based Game-Testing AI, in collaboration with Microsoft XBox team.
