A photo of myself

Hi! I am Yiu-Fai (Frankie) CHEUNG 張耀輝. 👋🏻

I am a first-year M.Phil. student in Department of Computer Science and Engineering at the Chinese University of Hong Kong (CUHK), advised by Prof. Irwin King.

I received my Bachelor’s degree with First Class Honors in Computer Science at CUHK, as a member of the ELITE Stream of the Faculty of Engineering.

My research interest includes Large Language Models, AI Agents and Multi-Agent Systems.

I feel very fortunate to have the opportunity to work under the supervision of Prof. Wenxuan Wang at Renmin University of China and Prof. Hao Wang at Stevens Institute of Technology.
