I am researcher (wissenschaftliche Mitarbeiterin) at Humboldt Universität and part of the group of Algebraic Geometry in the
Institut für Mathematik. My main research interests are the geometry of moduli space of vector bundles on algebraic curves, Brill-Noether
theory, Abelian and Prym varieties. I am giving a talk in the Brill-Noether Day at the Frei Universität on Thursday 3.11.
This year I visited the Isaac Newton Institut in Cambrige in the context of the program "Moduli spaces" (4 January -1 July 2011).
This semester the NoGAGS seminar will take place in Leibniz Universität Hannover .
