Research Summary

My research focuses on micropalaeontology of late Mesozoic (Late Jurassic - Early Cretaceous) non-marine deposits. Central aspects of my research are the taxonomy, phylogeny, palaeobiology and biostratigraphical application of ostracods (microcrustaceans of around 1mm size with a calcified bivalved shell, the carapace => Download little ostracod movie).

             Furthermore, I am interested in palaeoclimatology, particularly in climate-mode shifts, short-term climate changes, ocean-land interactions, and applications of these, such as marine to non-marine stratigraphic correlations.
