My research seeks to architect dependable and high-performance networked systems. I study Internet routing and transport protocols, peer-to-peer systems, wireless networks, and fault-tolerance and security. My research aims to build practical systems as well as to apply theoretical techniques to understand these systems. Check out some recent papers and drafts below.
