Harold Haodong Chen

Biography

I am a PhD student at Dept. of CSE, HKUST, supervised by Prof. Qifeng Chen. I am currently interning at Tongyi Lab@Alibaba Group, working on generation.

My current research interests focus primarily on Visual Generation/Reasoning and Code-for-Vision. Feel free to email me if you are interested in working with me :-)
