I am now at ThousandEyes in San Francisco. Read our Blog to get in depth insights on recent outages and events affecting the Internet infrastructure.

Research Summary

I am a postdoctoral researcher working in the Internet Research Lab at UCLA. I finished my Ph.D. at UCLA in Summer 2007 under the supervision of Prof. Lixia Zhang and Dr. Dan Massey. My Ph.D. research focused on understanding behavior of large scale distributed systems. In particular, I am interested in design and analysis of routing protocols. One of the outcomes of this work is Link-Rank, a tool to understand BGP routing changes and identify and diagnose problems in the Internet. I am also interested in automated attack detection and security in large scale systems. PHAS is a project to alert about prefix hijacking incidents in the Internet.
