I am currently a Senior Researcher at Microsoft Research Asia (MSRA), which I joined in late 2021. My research spans multimodal AIGC, 3D vision and embodied AI, with an emphasis on digital humans, 3D generation and reconstruction.

Feel free to contact me if you’re interested in my research, collaboration, or internship opportunities.
