I'm a Ph.D. student at UCLA in the department of Computer Science and a member of the Internet Research Lab under the supervision of Lixia Zhang. My research interests are in understanding and modeling the connectivity of different networks mainly at the inter-domain level; design of next-generation inter-domain routing architectures; control and data plane measurement and monitoring; lately I've also been working in traffic anomaly detection. I have been fortunate to collaborate with Walter Willinger and Dan Pei at AT&T Labs Research; Christophe Diot and Fernando Silveira at Thomson Research; Renata Teixeira at LIP6; Beichuan Zhang at University of Arizona; Mohit Lad at UCLA.
Projects
Cyclops: Cyclops is a system that provides ISPs a view of how their connectivity is perceived from hundreds of vantage points across the network, enabling a comparison between their observed connectivity and their intended connectivity. Among other things, it enables the detection of BGP misconfigurations, route leakages or false AS-link hijacks.

Internet Topology Collection: annotated AS level Internet topology map collected from several sources, including BGP routing tables+updates, route servers, looking glasses.
