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.

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.
