Prior to joining the Indian Institute of Science in 2011, I was an Associate Professor in the Department of Mathematics and Statistics at Queen's University.

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.

Research Interests

• Coding for Data Communication and Storage
• Information-Theoretic Security
• Source Coding, Data Compression, Data Synchronization
• Symbolic Dynamics
• Discrete Applied Mathematics (a broad umbrella for much of what I do)

Mandatory Reading/Viewing Material for Mathematicians

The Unreasonable Effectiveness of Mathematics by Richard W. Hamming. This essay was inspired by Eugene Wigner's original article, The Unreasonable Effectiveness of Mathematics in the Natural Sciences, Comm. Pure Appl. Math., 13 (Feb. 1960).

A Mathematician's Apology by G.H. Hardy. The classic defence of (pure) mathematics.

A lecture video on How to Write Mathematics by Paul R. Halmos, with an introduction by Don Knuth. (There was an article by Halmos on this topic available online at one point, but it seems to have vanished off the tangle of the web.)
