Harold Haodong Chen

Biography

I am a PhD student at The Hong Kong University of Science and Technology, supervised by Prof. Ying-Cong Chen and Prof. Qifeng Chen. I am currently interning at Tongyi Lab, working on world model.

We are always looking for self-motivated undergrad/master/mphil students for research projects in Visual Generation/Reasoning, World (Action) Models, and Agentic Applications. Feel free to ping me via Email or WeChat if you are interested in working with me :-)
