Research Interests/Expertise:

  • Micropaleontology of Mesozoic and Cenozoic Ostracoda (and Charophyta) with focus on Mesozoic non-marine deposits (Upper Jurassic–Lower Cretaceous) of the world
  • Integrated Stratigraphy (incl. biostratigraphy, chemostratigraphy, cyclostratigraphy) with focus on the Cretaceous
  • Fundamentals, principles and methods of the biostratigraphic application of (late) Mesozoic non-marine Ostracoda
