OpenPGP public key

Professor in mathematics.

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

Algebraic geometry at UiS

The algebraic geometry group consists, as of 2015, of Michal Kapustka (associate professor) and myself, Magnar Dale (emeritus) and a variable number of postdocs/PhD candidates. We run a weekly seminar.

During 2014--2018, the group hosts the project sheaves on abelian varieties, funded by the Research Council of Norway.
