About

I am Zhenxin Ai (艾振欣). I will soon pursue my Ph.D. at the Hong Kong University of Science and Technology (Guangzhou), advised by Assistant Prof. Haiyun He. I received my B.Eng. in Artificial Intelligence from Jiangxi University of Science and Technology, where I was advised by Prof. Huilan Luo. During my senior year, I was a visiting student at Westlake University, working with Assistant Prof. Huan Wang. My research interests include watermarking for multimodal large language models and world models. I am always open to related collaborations. If you are interested in discussing potential projects, please feel free to contact me via email.
