About Me

Hi, I am Jun ZENG. I earned my Ph.D. degree (advised by Prof. Zhenkai LIANG) from the National University of Singapore in 2023. I received my B.E. degree in Computer Science at the Huazhong University of Science and Technology in 2018.

My research interests lie in the interactions of system security, program analysis, and AI for security. Currently, I focus on threat hunting using graph computing and large language models for security applications.

Apart from Computer Science, I enjoy playing DOTA2 (Ranking: Divine), traveling and watching movies.
