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 Grassmannians, flag varieties, and affine Deligne-Lusztig varieties using the methods of algebraic combinatorics and combinatorial representation theory. Related interests include the study of the partially ordered set of Newton polygons associated to elements in the affine Weyl group, the development of models for quantum and affine Schubert calculus, and affine Hecke algebras.
