About

I'm a research fellow at National University of Singapore (NUS), hosted by Prof Abhik Roychoudhury. Before that, I received my doctoral degree from Tsinghua University, advised by Prof Yu Jiang, and BS degree from Beijing University of Posts and Telecommunications (BUPT).

Research

My research focuses on ensuring the security and privacy of real-world systems (e.g., network protocols, IoT platforms) through program analysis, software testing, and reverse engineering techniques. Currently, I am exploring how LLMs can revolutionize these methods with superior reasoning capabilities and cross-domain scalability.

📢 Openings: I am looking for self-motivated students and researchers! If you are interested in joining as a research assistant or visiting scholar, feel free to drop me an email with your CV.
