I was director of the Centre of Mathematics for Applications CMA since the start in 2003 to 2013. CMA was one of the first thirteen Norwegian centres of excellence supported by the Research Council of Norway. From 2004 to 2010 I was serving as chairman of the board of the Niels Henrik Abel Memorial Fund.
My research interests are partial differential equations and numerical analysis. In particular, lately I have focused on the development of compatible discretization methods , in particular on finite element exterior calculus.
