The primary field in my Ph.D. studies are multigrid methods, especially in the application field of molecular dynamics. In that field there are several specific challenges, such as unbound domains, long-range interactions or singularities playing a major role. I develop new approaches for coping with those issues, e.g. hierarchical coarsened grid structures. Emphasis is put on algorithmical efficiency and the parallelization on modern architectures.
