About Me:
I am an RTG postdoctoral scholar at the University of Oregon working under the supervision of Nicolas Addington. My research interests are in algebraic geometry, and they include hyper-Kaehler geometry, moduli spaces of sheaves, and derived categories.
Recently, I received a Ph.D. from the University of Massachusetts Amherst under the supervision of Eyal Markman.
