I am a 2nd-year graduate student in math at The University of Oregon. I am interested in categorical and geometric representation theory, and in their connections to low-dimensional topology and mathematical physics. My advisor is Ben Elias. Previously I was an undergraduate in physics and mathematics at The University of Texas where I did a senior thesis on the Springer correspondence, supervised by Sam Gunningham.
In the Winter 2019 quarter I will be a mentor for the directed reading program (DRP). I hope to pay forward the positive experiences I had as a mentee in the DRP at The University of Texas.
In arXiv:1811.06188 B. Elias initiates a research program giving a Soergel bimodules analogue of D. Gaitsgory's construction of central perverse sheaves on affine flag varieties, which we call Gaitsgory's Central Sheaves (GCS). In short this program aims to associate a central complex of Soergel bimodules of (extended) affine type A to any finite dimensional representation of SL_n. This is achieved in all rank for the defining representation. We call these Gaitsgory's Central Complexes. Another outcome of this program is to give a Soergel bimodules analogue of the so-called flattening functor from the affine Hecke category to the finite Hecke category. This functor categorifies the flattening map from the cylindrical braid group to the ordinary braid group.
In a twist of fate, the flattening of the Gaitsgory's Central Complex associated to the defining representation of SL_n is sought after in work of E. Gorsky, A. Negut, and J. Rasmussen (GNR) conjecturing an equivalence between the Drinfeld center of the Hecke category of type A and coherent sheaves on the Hilbert scheme of n points in the plane. It is expected this complex corresponds to the tautological bundle on the Hilbert scheme.
In view of (GNR), I am attempting to give a formula for the endomorphism X of the tautological bundle on the Hilbert scheme as a morphism of the Gaitsgory's Central Complex associated to the defining representation. (in writing)
In Spring 2019 I am teaching Math 112 - Precalculus. The course website is here.
