Network measurement, Internet topology and routing.
I am a Ph.D Candidate in the Department of Electrical and Computer Engineering at University of Maryland. I am interested in measuring the Internet: its topology, performance and dynamic nature.
Before joining UMD, I received my B.Eng. degree in the Department of Electronic Engineering at Tsinghua University in 2012.

- D-Root DNS Server
Measurement and analysis of the query traffic sent to the D-Root DNS root nameserver, which is hosted by University of Maryland.
- DeTor: Provably Avoiding Geographic Regions in Tor
DeTor is a set of techniques for proving when a Tor circuit has avoided user-specified geographic regions.
- Alibi Routing
Alibi Routing is a peer-to-peer system that allows users to understand and control where in the world their packets don't go.
- Alias Resolution in IPv6
UAv6 is a state-of-art alias resolution technique for IPv6.
