About

I am building stuff. Previously, I was a Team Lead at Tencent Hunyuan, where I was responsible for developing Hunyuan Image Editing models (now powering Yuanbao, Tencent Games, Tencent Videos, etc), HunyuanImage 3.0 post-training, and a few application models. Before that, I was a Principal Researcher at Microsoft Research Asia working on computer vision. I serve as area chair and reviewer for a few top computer vision and machine learning conferences, and received the AAAI Best Paper Award in 2026. I obtained my PhD degree from Peking University.
