My research area is called Operator Algebras. It includes C*-algebras and von Neumann algebras, and is traditionally classified as a part of Functional Analysis. I am also interested in Harmonic Analysis and Linear Algebra

If you want to know more about my activities, you can have a look at my CV (in norwegian, and only updated from time to time).

My most recent research article is written together with Ulrik Enstad (Stockhom) and Jordy T. Van Velthoven (Delft), and called Reproducing properties of lattice orbits of nilpotent Lie groups and strict comparison of projections.

Concerning my teaching activities the recent years, you should consult my web-page in norwegian.
