My original research interests were in the Schubert calculus, which is at the interface of algebraic geometry, representation theory and algebraic combinatorics. Over the years, this has evolved in many directions, including real algebraic geometry, computational algebraic geometry, Hopf algebras in combinatorics, and discrete and computational goemetry. Currently, I have research projects in each of these areas, and have projects involving about two dozen collaborators.

    More information may be found browsing my web page; I particularly recommend some mathematical short stories or some more involved web pages that I have created in the course of my research.
