Hi, there!

I am an associate research fellow at Zhongguancun Laboratory, focusing on network security and Internet measurement, with particular interests in security of the Domain Name System (DNS) and other infrastructure.

I'm also serving as member of the Security and Stability Advisory Committee (SSAC) of ICANN.

Previously, I was a postdoctoral researcher at Tsinghua University from 2022 to 2025, reporting to Prof. Haixin Duan.

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.
