I am a research staff member at ZGC Lab, Beijing. I received my Ph.D. with honor from Network and Information Security Lab (NISL) at Tsinghua University (advised by Prof. Haixin Duan) in 2023.

My research focuses on measuring and enhancing the security of Internet infrastructure (DNS, Web PKI, CDN, etc.), uncovering significant vulnerabilities in core protocols (DNS, HTTP, TLS, etc.), and understanding emerging cyberspace security threats.
