Bio & CV

My current research interests span cloud computing, online and mobile social networks, peer-to-peer networks, and wireless networks. I am interested in algorithm design and performance modeling of various distributed systems based on a variety of theories, including optimization, game theory, graph theory, and network coding. I am also interested in measurement and implementation of real-world networking systems.
