Prior to joining the Indian Institute of Science in 2011, I was an Associate
Professor in the Department of
Mathematics and Statistics at
I have a PhD in Electrical Engineering: Systems and an MS in Mathematics from the University of Michigan (2001), and a BTech in Electrical Engineering from IIT Bombay (1995).
A little more detail on my prior academic background and experience is provided on
a separate page.
I currently serve on the editorial boards of the SIAM Journal on Discrete Mathematics, and Cryptography and Communications.
I have previously served as an Associate Editor for Coding Theory for the IEEE Transactions on Information Theory.
I am a past recipient of the DST Swarnajayanti Fellowship in the Engineering Sciences.
