Research

My research program explores interactions between modern methods in algebraic geometry, algebraic combinatorics, and representation theory.  In particular, I am interested in answering geometric and topological questions about algebraic varieties such as the flag variety, the affine Grassmannian, and affine Deligne-Lusztig varieties using the methods of algebraic combinatorics and combinatorial representation theory.  Related to these projects is the study of the partially ordered set of Newton polygons associated to elements in the affine Weyl group, as well as the development of models for quantum Schubert calculus.
