Hongxu Chen(陈鸿绪)

I am a first-year PhD student in the Department of Computer Science and Engineering at the Hong Kong University of Science and Technology (HKUST), advised by Prof. Long Chen. I received my bachelor’s degree from the School of the Gifted Young, University of Science and Technology of China (USTC), where I conducted research under the supervision of Prof. Zhenya Huang.

My current research focuses on generative modeling (e.g., flow matching and diffusion models). Previously, I worked on model merging and parameter efficient fine-tuning.

Please feel free to contact me if you have any questions about my projects or anything else.
