Hi! I am professor at the department of computer science and engineering and the Dean of Resource, Planning and Generation (DRPG) at the Indian Institute of Technology, Kanpur. I am also the recipient of the first Infosys Prize for Mathematics. I obtained a B.Tech. and a Ph.D. at IIT Kanpur and attained my undergraduate degree between 1982 and 1986.

I co-created the AKS primality test with Neeraj Kayal and Nitin Saxena, for which my co-authors and I won the 2002 Clay Research Award, the 2006 Fulkerson Prize, and the 2006 Gödel Prize. The test is the first deterministic algorithm to test an n-digit number for primality in a time that has been proven to be polynomial in n.
In September 2008, I was chosen for the first Infosys Mathematics Prize for outstanding contributions in the broad field of mathematics.
