electrical and computer engineering in 1997, and a Ph.D. degree in
Electrical and Computer Engineering in 2000, all from Rice University. He joined the faculty
of Purdue University in August 2004. Prior to that, he had served
as an assistant professor at Rice University (2001-2004) and as
a senior developer at iMimic Networking
(1999-2001). He received the NSF CAREER award in 2003 and
the Wilfred "Duke" Hesselberth Award for Teaching Excellence in 2007.

performance evaluation. He was a primary developer and
maintainer of the publicly-available
Rice Simulator for ILP
Multiprocessors (RSIM). Vijay is a member of the
Eta Kappa Nu,
Phi Beta Kappa, and
Tau Beta Pi honorary societies, and his
graduate education was partly supported by a
Fannie and John Hertz Foundation
Fellowship.
