Superintelligence@Meta
I'm a Research Scientist at Meta (TBD Lab). Previously I was a Research Scientist on the Google DeepMind Gemini team, building some awesome generative models (Gemini Omni and Nano Banana Pro). Before that, I co-led the diffusion-distillation efforts at NVIDIA.
I received my PhD @ MIT EECS, advised by Tommi Jaakkola, and my BS from the Turing Class in EECS @ Peking University, working with Yizhou Wang (PKU) and Stefano Ermon (Stanford). During my time at GDM I worked with Tim Brooks; at NVIDIA I worked with Arash Vahdat and Ming-Yu Liu.

Miscellaneous
I'm a national second-class table tennis player in China and the men's singles champion of the PKU Freshman's Cup (2016). I also played for the MIT table tennis team, taking 3rd place (group) at the 2022 NCTTA Upper New England Championship. 🏓
