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 new five year Simons Foundation Collaboration grant effective July 2016.

My previous five year Simons Foundation Collaboration grant began July 2011. Six collaborators and nine graduate students received funding via this grant. My graduate student Yue Cai also received funding for a research visit to Princeton in Fall 2014.

During the academic year 2014--2015 I was a Visiting Professor and Research Scholar in the Princeton University Mathematics Department.

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.

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