Academic Bio

I received my Ph.D. in Electrical and Computer Engineering from the University of Illinois at Urbana-Champaign in December 2011. At UIUC, I was a member of the Decision and Control group, which is part of the Coordinated Science Lab (CSL). My Ph.D. advisor was Professor RS Sreenivas. My previous degrees include an M.S. in Electrical and Computer Engineering from UIUC, and a B.Tech. in Electrical Engineering from IIT Madras in 2005.

Other Affiliations

During my Ph.D., I also held temporary visiting appointments/internships (in r.c.o.) at Microsoft Research Cambridge, Complex Systems Group at Bell Labs, ALGO Lab at EPFL and the Technicolor Corporate Research Lab in Paris.
