Tianyu Yang

I am a Researcher at Meituan. Prior to that, I worked at Alibaba DAMO Academy, IDEA, and Tencent AI Lab. I received my PhD from City University of Hong Kong, advised by Prof. Antoni B. Chan.

My research interests lie in visual generative modeling, 3D vision, representation learning, and video understanding. Recently, I have been working on video generation.
