Research Interests

I am broadly interested in Algebraic and Enumerative Combinatorics, in particular with connections to Geometry and Representation Theory.

I currently work on representations of reflection groups on splines, posets of maximal tubings, expansions of the chromatic quasisymmetric function, and questions related to the cohomology of Hessenberg- and other GKM-varieties.
