Research Interests: Rapid climate change during the Quaternary – Climate change and global biogeochemical cycles during the Neogene – Time-series analysis

We study the environmental conditions and their variability throughout the Earth’s history by means of Earth-system models. These are computer programs, which allow us to investigate the mechanisms underlying reconstructed environmental variability, resulting from the interactions of atmosphere, ocean, sea- and inland ice, as well as the marine and terrestrial biosphere. Specifically, we analyse the origin of natural climate variations to assess the stability of the climate system at different times in the geological past.

Working Area

Origin and course of ice-age cycles – natural climate variations during the present warm phase – climate development during the Neogene (i. e., the past 24 million years of Earth’s history) – direct modelling of measurable climate indices (e. g. oxygen- and carbon isotopes) – climatically relevant biogeochemical cycles – climate-induced variations of marine ecosystems.


The employed Earth-system models are complex computer programs, describing the dynamics of atmosphere, ocean, sea-ice etc., biogeochemical processes and their interactions. The range of models encompasses detailed, realistic models, models with reduced complexity, as well as conceptual models, which allow for a deeper understanding of the climate system by focusing only on the essential dynamical elements of the climate system. Numerical experiments are carried out on high-performance computers.
