Research Interests:

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 .

For more about my research, please see my papers and collaborators (including people at UIUC I have worked with), or see:
