I am an Associate Professor at Prof. Guan Yuan’s group, School of Computer and Science, China University of Mining and Technology (CUMT). I received my Ph.D. degree from Kyoto University in 2024, supervised by Prof. Yang Cao and Prof. Masatoshi Yoshikawa. My current research focuses on Privacy and Security, Graph Analysis, LLM . Please contact me if you are interested in any form of collaboration.
