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

  • Cretaceous greenhouse climate, Mesozoic climate shifts and climate extremes
  • Mesozoic evolution of non-marine/terrestrial habitats
  • Ostracod biostratigraphy, palaeoecology, palaeobiogeography, phylogeny
