About me

I am currently working as an Algorithm Engineer at Seed-Application-Vision, ByteDance, focusing on DiT-based video generation and digital human tasks.

I obtained my B.S. degree in Mathematics and Physics from Tsinghua University in 2018, and my Ph.D. degree in the Department of Automation from Tsinghua University in 2023, advised by Yebin Liu in Institute for Brain and Cognitive Sciences.

My research interests lie in DiT-based video generation, digital human, 3D body reconstruction, 3D face reconstruction, 3D face tracking, StyleGAN-based or NeRF or 3DGS-based facial avatar and diffusion-based human generation.

FlowAct-R1: Real-time talking avatar.
Real-time tracking (single RGB camera).
Real-time portrait avatar.
