G reetings!

I am a
Professor of Mathematics
at the
University of Kentucky.

Here is my Princeton website.


I am a member of the Discrete Mathematics group in the Department of Mathematics at the University of Kentucky.

I have been awarded a five year Simons Foundation Collaboration grant beginning July 2011.

During the academic year 2010-2011, I was a Member in the School of Mathematics at the Institute for Advanced Study in Princeton.

During the academic year 2006-2007, I was on sabbatical leave at MIT.

Curriculum Vitae


My research interests are in algebraic combinatorics, namely the interaction of combinatorics with algebra, topology and discrete geometry.
