G reetings!

I am a
Professor of Mathematics
at the
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.

Curriculum Vitae


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

Recent preprints and papers

My Father

Arthur F. Readdy, Jr. (March 4, 1928 - March 2, 2008)


I am the organizer of the Discrete CATS Seminar (where CATS = Combinatorics Algebra Topology and Statistics!) This was formerly the University of Kentucky Algebraic Combinatorics Seminar.

I am also the organizer of the UK WILDCATS Seminar .

PhD Students

Patricia Muldoon Brown, PhD 2009, "Rees Products of Posets and Inequalities" (pdf).

Yue Cai has begun to do research with me. She has been awarded a Summer 2012 Research Fellowship from the University of Kentucky Department of Mathematics.


I have been a Faculty Advisor for two REU's at Cornell, one in 1997 and the other in the summer of 2000. Here you can see an article about the Summer 1997 REU.

Here is a list of my REU students.

My student Michael Levin, a 2001 graduate from Harvard, won Honorable Mention for the 2001 Morgan Prize.


Here I am asking Professor Einstein why he hasn't been showing up for tea lately at Fuld Hall.

Here is a recent picture of my sons Thomas and Theodore, ages 6 and 10. And ages 8 and 12.
