Welcome to my personal homepage

I am currently working at Telefonica Research in Barcelona. My new webpage is at TID.

I was a graduate student at the Computer Science Department of the University of California, Riverside. I graduated from UCR with a Ph.D. in Sept. 2005. The title of my dissertation was: "Analyzing the Cooperation of ISPs in Internet Routing: Security Implications and Accurate Internet Models". My supervisor was Michalis Faloutsos.
