Research Interests

Network measurement, Internet topology and routing.

About me Linkedin

I obtained my Ph.D degree in the Department of Electrical and Computer Engineering at the University of Maryland, advised by Prof. Neil Spring. I also work extensively with Prof. Dave Levin and Prof. Bobby Bhattacharjee.

I am interested in measuring the Internet: its topology, performance and dynamic nature. Specifically, my dissertation research focuses on understanding the interactions between interdomain routing and IP anycast, and improving the performance and reliability of critical anycast-based Internet infrastructure that affects millions of gloabl Internet users. I also work on security and privacy problems around Internet routing.

Before joining UMD, I received my B.Eng. degree from the Department of Electronic Engineering at Tsinghua University in 2012.
