Our main research interest is the reconstruction of atmospheric and climatic conditions in the past using ice cores from high-mountain glaciers. Current projects include:

  • Reconstructing paleo fires based on the analysis of black carbon and specific molecular tracers
  • Determining the effect on chemical impurities on the darkening of glaciers
  • Studying the location of chemicals in ice crystals
  • Estimating the release of pollutants from melting glaciers
  • Investigating the emissions of heavy metals from mining activities
