Welcome

(New: daily meditations.)

I'm an assistant professor at the University of Georgia. I'm part of the algebra research group.

My research lies in an area of algebra called geometric representation theory. I enjoy thinking about categories of perverse and coherent sheaves coming from some Lie theoretic data. Keywords related to things I've been thinking about include affine Grassmannian, affine flag manifold, exotic sheaves on the Springer resolution, generalized Springer correspondence, geometric Satake, Lusztig's character sheaves, modular representation theory, and Whittaker sheaves.. 

I completed my Ph.D (08.09.13) under the direction of Pramod Achar at Louisiana State University. My thesis work involved proving formality for the Springer block of (constructible) sheaves on the nilpotent cone. This required the construction of a suitable mixed version of the (equivariant, l-adic) category of sheaves on the nilpotent cone. You can find a copy of my thesis here.
