My research interests include combinatorics (including
umbral calculus), representation theory, and symbolic computation, and
the relationships between these fields.
 
My mathematical genealogy
My thesis advisor, Gian-Carlo Rota, passed away on April 18, 1999. One
of my mathematical siblings keeps part of our mutual mathematical
family tree. Shortly after his death, I wrote down some remembrances
of my advisor. They were collected with the thoughts of numerous other
students and colleagues by the SIAM newsletter on Discrete Mathematics.
Research Overview
Determinants, Representation Theory, and Symbolic Computation
Combinatorics, among many other things, involves the study of (partially)
ordered structures, and some of my favorite questions center on understanding
what happens when one takes an algebraic structure and imposes a "compatible"
order. A relatively familiar example of this situation is Groebner basis
theory in which an ideal in a polynomial ring may be studied (both theoretically
and computationally) via the imposition of a total order on the monomials
in the ring. My research in this area uses Straightening Laws and other
variants of the above techniques to study representations of the general
linear group corresponding to "row-convex diagrams." A brief (11 pages)
but fairly readable introduction to this material may be found in my FPSAC
'97 abstract "Straightening
laws for row-convex tableaux," also available in a postscript
and DVI.

Umbral Calculus
Another useful technique in algebraic combinatorics involves the imposition
of an algebraic structure on a combinatorial problem. A very particular
example of this is the umbral
calculus in which complicated identities in a vector space, V,
are derived by working in a polynomial ring which projects down onto V.
My publications in the area appear below (in preprint format).
