About me

I am an associate professor and the undergraduate director in the department of mathematics at Illinois State University. I also hold research assistant professor positions in the mathematics departments at UIUC, and at Western University in Canada.

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 ISU Putnam homepage.



  1. Keir Lockridge and I have organised an AMS special session on "Triangulated categories and their associated cohomology theories" at University Park, PA on October 24-25, 2009.

  2. George Seelinger and I have organised the Fall Midwest Topology Seminar at ISU on Saturday, October 8th, 2011.
