About Me

I am a new assistant professor in the Department of Computer and Information Science at the University of Pennsylvania. Before Penn, I got my Ph.D. at the University of Washington working (primarily) with Tom Anderson and Arvind Krishnamurthy. Before that, I received my B.S. in Computer Science at the University of Texas where I worked with Calvin Lin.

My research interests are in the broad areas of distributed systems and networking, but include a number of related topics. To borrow a phrase from one of my advisers, Tom Anderson, "I see myself as a generalist -- I am attracted to the biggest problem I can find, regardless of area." To this end, my projects have touched on fault-tolerance, security, data centers, wireless networks, clean-slate Internet architecture, routing/addressing, and the economic aspects of the Internet. My undergraduate research was in the area of compilers and parallel systems.

Students

I also work closely with John Sonchack (student of Johnathan Smith), João Sedoc (student of Lyle Ungar), and Max Demoulin (student of Linh T. X. Phan).
