Research Description
My research interests are in combinatorics, in relation to algebra, geometry, Lie theory, probability, algorithms and other areas of mathematics. The core of my research program has been in Schubert calculus and geometry. Other work I have done may be roughly classified under combinatorial commutative algebra and combinatorial algorithms.
