The group uses a range of sedimentological, mineralogical, biogeochemical and paleontological proxies in lake sediments and statistical tools to investigate long-term climate and environmental variability and change. The spotlight of investigation is currently on very high-resolution (seasonal to annual), quantitative climate reconstructions, process studies and pollution history covering the industrial period, the last Millennium and the late Holocene. The Swiss Alps, Central Europe and the southern Hemisphere are the main areas of interest. Research is typically highly interdisciplinary.
The group is a member of the Oeschger Centre for Climate Change Research, University of Bern and participates in the IGBP-PAGES Past Global Changes programme.
