Research Profile

My main research interests are related to algebraic K-theory and motivic homotopy theory in the sense of Morel-Voevodsky. I am in particular interested in generalized algebraic cohomology theories representable in the motivic stable homotopy category, e.g. Hermitian K-theory, Witt groups and algebraic cobordism.
