My research has been primarily focused on issues arising in network information theory and combinatorial optimization problems. I have also been involved in the analysis of algorithms arising in the above areas as well as some originating in queuing theory, networks, energy-efficient scheduling in sensor networks, etc. Most of the above research has been motivated by a seemingly innate attraction towards certain problems containing elements of probability and combinatorics.
For the last few years my research has primarily focused on some fundamental unresolved issues in network information theory. Before this my research mainly dealt with theoretical issues connected to combinatorial optimization problems in both finite and large systems, primarily motivated by conjectures posed by statistical physicists. Apart from these two long-term affairs, I have also had brief fancy for a bunch of isolated issues, mostly as a collaborator with some very interesting colleagues.

Since Fall 2007 I have been an assistant professor in the Information Engineering(IE) department at the Chinese University of Hong Kong. From Fall 2008 I am also serving as an assistant director of the Institute of Theoretical Computer Science and Communication(ITCSC). Recently I have a courtesy appointment in the Computer Science and and Engineering (CSE) department.
From Summer 2005-Summer 2007 I spent two wonderful years in Redmond as a post-doc with the theory group at Microsoft Research. It was during this period that I changed my research focus from Combinatorial Optimization problems to Network Information Theory.
I did my undergraduate studies at the Indian Institue of Technology(IIT ), Madras in electrical engineering graduating in 1999. Concurrently, I also completed the four year nurture programme in Mathematics at the Institute of Mathematical Sciences(IMSc ) under the auspices of the National Board of Higher Mathematics(NBHM).
I received a Masters (2002) and PhD (2005) in electrical engineering from Stanford University. The title of my dissertation was Proofs of the Parisi and Coppersmith-Sorkin conjectures in the random assignment problem (PDF), and Balaji Prabhakar was my advisor. Following my postdoctoral position at the theory group in Microsoft Research, I joined the IE department faculty in CUHK.
