Hi, there!

I am a postdoctoral researcher at Network and Information Security Lab (NISL) of Tsinghua University, reporting to Prof. Haixin Duan.

I focus on network security and Internet measurement, with particular interests in security of the Domain Name System (DNS) and other infrastructure.

I obtained my PhD from Tsinghua University in 2022 (Advised by Prof. Jianping Wu), and my BSc from Beijing University of Posts and Telecommunications in 2017.
