Algebraic and geometric combinatorics

I am interested in the interplay between algebra, geometry and combinatorics. The overarching theme of my current research is to develop a new perspective on classical multivariate polynomials by recasting them in terms of polytopes. In recent work with collaborators we show a close connection of flow polytopes, generalized permutahedra and Schubert polynomials, thereby bringing new ideas to study these and related polynomials.
