Research Interests
My research area is geometric representation theory. I am currently thinking about the wonderful compactification and applications to quantum groups. Another interest is quantizations of multiplicative hypertoric and multiplicative quiver varieties, especially at roots of unity, as instances of the general framework of Frobenius quantum moment maps. I am also interested in deformations of category O for rational Cherednik algebras and relations to sheaves on moment graphs.
My advisor is David Ben-Zvi. My collaborators include David Jordan, Nicholas Cooney, Emanuele Ghedin, and Jacob Matherne.
