Shen Sang (桑燊)

I am a Senior Research Scientist, with a primary focus on virtual human and GenAI, at the Intelligent Creation Lab, TikTok.

I received my master's degree from UC San Diego. I was fortunate to work with Prof. Manmohan Chandraker at the Visual Computing Center.

Research

I work on human-specific image and video generation. My current research interests include customized video generation, personalized image generation with diffusion models, and enhancing the training and inference efficiency of these models. Previously, I worked on 3D vision and graphics, particularly in 3D reconstruction and neural relighting.
