RESEARCH
My research interests are in information and coding theory, wireless communication and networks. I am interested in understanding the fundamental limits of communication in wireless networks and deriving principles for wireless network design. In particular, I am interested in capacity scaling laws and cooperation in large networks and approximate capacity characterizations for relay networks. I am also interested in the challenges involved in translating such fundamental principles to practice. In particular, I am interested in network complexity reduction via wireless network simplification and lowcomplexity code design for wireless relaying.
