 I have just joined the faculty in the math department at Rutgers University,  and was formerly a member of the AGANT group in the math department at UGA.  My recent work has focused on conformal blocks, and the development of new methods for their use in studying the geometry of moduli spaces of pointed curves as well as moduli spaces of sheaves on curves. This work has been funded by two personal NSF grants “Conformal blocks and positive cycles on the moduli space of curves,” (2012-2016) and “Vector bundles of conformal blocks on \overline{M}_{g,n},” (2016-2020).  In earlier work, I studied aspects of the moduli space of curves using Mori theory and tropical geometry (funded by NSF DMS-050931).
