Paleobiology of the cephalopods Our primary focus is on the paleobiology and phylogeny of nautiloids, ammonoids and coleoids [Video: "First observations of a snail-like body pattern in juvenile [Sepia bandensis (Cephalopoda: Sepiidae)]
Calcareous dinoflagellate cysts We study the phylogeny of "calcispheres" and their contribution to paleo-oceanographic issues.
Ostracods and charophytes We focus on applied research in the fields of biostratigraphy, biogeography, paleoecology and climatology.
Reef evolution and ecology Sea-level fluctuations during Earth's history, evolution of Mesozoic marginal basins, formation of microbial carbonate rocks, interdisciplinary Anthropocene studies.
Upper Cretaceous stratigraphy and oceanography Stratigraphy and paleoecology of Upper Cretaceous shelf seas.
Cenozoic snails Research on their systematics and phylogeny as well as their application primarily in the context of paleoclimate and human history.
Ancient lakes and climate history Research on evolution and climate history relating to several ancient lakes (e.g. Lake Baikal) and Early Cenozoic ecosystems in general. Focus on Central Asia (e.g. the Tibetan Plateau) as well as other regions of the Earth. We study many different groups of fossils (but mainly molluscs).
Spores and pollen (palynology) Reconstruction of Late Quaternary vegetation and climate, focusing on Central Asia and Siberia.
Taphonomy of fossil lagerstätten We study fossil sites where organisms – including soft parts – are unusually well preserved. The present focus is on the Cambrian of China (Chengjiang).
Biogeoscience Coral Reefs: - Use of proxies (growth rates, carbonate production, stable isotopes) in corals to reconstruct environmental change in the Holocene and Anthropocene - Effects of climate change on reef ecosystems - Human impact, marine conservation, volunteer involvement in science
Palynological studies in order to reconstruct palaeovegetation and to understand monsoon variabilities during the Holocene in northwestern India. This task is conducted as part of the DFG Research Unit "Himalayas: Modern and Past Climates (HIMPAC)"
Development of sampling equipment for water, porewater and sediment samples
Analysis of environmental samples from point and diffuse sources for organic and inorganic compounds, contaminant identification in combination with ecotoxicological analysis, ecological risk assessment
Analysis of marine microplastics within the Expedition-MED and MP in urban ecosystems
