I am a
Professor of Mathematics
University of Kentucky.
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.
For Spring 2011 I have been awarded a University of Kentucky Tenured Professor Benefit by the Dean of Arts & Sciences.
During the academic year 2006-2007, I was on sabbatical leave at MIT.
Richard Ehrenborg and I are the founders and organizers of the Math Movie of the Month.
My research interests are in algebraic combinatorics and discrete geometry.
