Washington: Indian-American computer scientist Subhash Khot, most well
known for his "Unique Games Conjecture", has received the prestigious
National Science Foundation's (NSF) $500,000 Alan T. Waterman Award.

The award is given annually to an outstanding young researcher in any
field of science and engineering supported by the NSF. The honour
includes a grant of $500,000 over three years for scientific research
or advanced study in any field of science.

An Indian Institute of Technology, Bombay graduate, Khot is associate
professor at the New York University's Courant Institute of
Mathematical Sciences.

A theoretical computer scientist, he works in an area called
"Computational Complexity" which seeks to understand the power and
limits of efficient computation.

"Subhash Khot is a gifted and ambitious young scientist," said NSF
Director Arden L. Bement, Jr.

"He courageously tackles some of the most challenging computational
problems, all the while advancing computer security, with vast
consequences for the broader security of our personal identities,
commercial interests, societal institutions...even for national
security as a whole.

"Subhash is a brilliant theoretical computer scientist and is most
well known for his Unique Games Conjecture," added Jeannette Wing,
assistant director for NSF's Computer Information Science and
Engineering (CISE) directorate.

"He has made many unexpected and original contributions to
computational complexity and his work draws connections among
optimisation, computer science, and mathematics."

Khot has made significant inroads to identifying "computational
intractability" or problems that cannot be solved fast. He has
uncovered a problem about probabilistic games called "the Unique Games
Problem". His work shows that it lies at the core of a variety of
intractable computational problems, NSF said.

Khot has received an NSF Career Award, a Sloan Foundation Fellowship,
and a Microsoft New Faculty Fellowship.

With his colleagues at NYU, Princeton, Rutgers University, and the
Institute for Advanced Study, he is part of a $10-million NSF
"Expeditions in Computing" grant under which the researchers are
seeking to bridge fundamental gaps in our understanding of
computational intractability.

Khot did his doctorate in computer science from Princeton University
in 2003.

Currently, an associate professor in the Department of Computer
Science at the Courant Institute, Khot was previously an assistant
professor at the Georgia Institute of Technology (2004-07).
