About Me

I am a researcher at Tencent Hunyuan, working on the HY World project. I received my Ph.D. degree from the Department of Computer Science, City University of Hong Kong (CityU), under the supervision of Prof. Rynson W.H. Lau and Prof. Gerhard Hancke. I received my B.Eng. degree from Xiamen University.

During my Ph.D. studies, I was fortunate to work with Tengfei Wang and Ziwei Liu from Shanghai AI Lab and MMLab@NTU. I was also lucky to closely collaborate with Nanxuan Zhao from Adobe Research.

I'm interested in generative AI, including world models, video generation, 3D reconstruction, and 3D asset generation.
