Professor in mathematics.

Research interests include abelian varieties, derived categories, geometric invariant theory and moduli spaces of sheaves.

I am a member of the Algebraic Geometry group at the University of Stavanger. During 2014--2018, the group hosts the project sheaves on abelian varieties, funded by the Research Council of Norway.
