Job description

I work in the interplay of mathematics and theoretical computer science. One focus of my reserach is on questions releated to computational complexity of algorithmical questions in real algebraic geometry and  optimization. Concretely, I  am interested in polynomial optimization, representation of positive polynomials by sums of squares, moment problems, quadrature formulas, algorithmic complexity, convex sets and semidefinite relaxation.

Please visit my Research Homepage for more details on reserach and preprints.

I am leading the Algebra group and I am also one of the initiators of the Lie-Størmer Center for Fundamental Structures in Computational and Pure Mathematics. I currently also serve as pro-dean at the faculty of science and technology with a focus on the PhD program.
