About me

I am currently a postdoctoral research associate at Imperial College London, working with Professor Deniz Gündüz on the project [Machine Learning and Information Theory].

I received my Ph.D. degree from The Chinese University of Hong Kong in 2025, advised by Professor Cheuk Ting Li and Professor Raymond W. Yeung.

I was a visiting scholar in Stanford University, ISL Lab, from January 2024 to June 2024, hosted by Professor Ayfer Özgür and supported by CUHK PhD IMPAC Award 2023–24.

I received my B.Eng. degree in Electronic Information Engineering and minor degree in Philosophy from The Chinese University of Hong Kong (Shenzhen) in 2021, advised by Professor Shenghao Yang.

Research

My research interests lie at the intersection of information theory, machine learning, and privacy. I develop novel techniques for non-asymptotic information theory and one-shot achievability results, and I also apply these techniques in various fields of artificial intelligence, including distributed machine learning, sampling problems, LLM inference, LLM watermarking, and generalization performance characterization of learning algorithms. In addition, I study several problems related to wireless communication and networking. I am always passionate about any form of collaboration and am happy to help or learn new things, so please feel free to contact me.
