### About

I am interested in problems of quantum field theories on curved spacetimes - in particular states in such theories - and questions concerning constructive problems of relativistic quantum field theory - in particular algebraic constructive methods (see page by Gandalf Lechner for more information). In both fields I am interested in thermal aspects; for generic curved spacetimes this necessarily means questions of local equilibrium, in more specialized situations and for self-interacting qfts also global equilibrium states are of interest.
