I am an associate professor and the undergraduate director in the department of mathematics at
Illinois State University. I
also hold a research assistant professor position in the mathematics departments at Univeristy of Illinous, Urbana-Champaign.
A brief history of my time since college: From 1995 to 2000, I attended the Indian
Statistical Institute (Kolkatta) where I got my Bachelors and Masters
degrees in Statistics with a specialisation in Advanced Probability.
Under the supervision of John Palmieri I got my Ph.D. in Mathematics at the University
of Washington, Seattle in 2005. My thesis was in the area of stable
homotopy theory. After completing my Ph.D., I had a 3-year
postdoctoral fellowship at the University of Western Ontario, Canada. I joined the Illinois
State University in Fall 2008.
My broad interests include Mathematics, Music, Physics, Astronomy, Cosmology,
Games, Logic, Computing, Philosophy,
and the History of Intellectual Thought.
My current Erdos number is 3: Erdos ---> John Conway ---> Dave Benson ---> Me. You can read about the
Erdos number here.
The homotopy type of my known mathematical genealogy is a wedge of three circles.
I love working with students. If you are a student who is interested in doing an Honors
project, a Masters thesis/project or an independent study/research in some
area of Mathematics under my supervision please contact me. I will be very happy to guide you.
I work on a bunch of different areas. Current interests lie in the
fields of Number theory, representation theory of groups,
Tate cohomology, and Galois cohomology. Visit my research page for more
information. My research is being currently supported by a grant from the National
Security Agency (NSA).
I am in-charge of the Putnam Mathematical Competition at
ISU. If you are an undergraduate student who loves solving math problems, you
should definitely take part in Putnam. For more information visit
