My research interests are in Algebraic Geometry. More specifically, I work with algebraic curves, vector bundles, and their moduli.  I am a part of the Algebraic Geometry group at UGA, a co-PI on the AGANT (Algebraic Geometry, Algebra and Number Theory) NSF RTG grant, and currently supported by NSF grant DMS-1201268 “Conformal blocks and positive cycles on the moduli space of curves.”
