Research Interest

  • General research areas are biogeochemistry, soil chemistry and soil degradation of natural and semi-natural ecosystems. Specifically the research is focused on:
  • Soil and water degradation by soil erosion. Quantitative and qualitative assessment of on-site erosion with radio- (137Cs and 239+240Pu) and stable (13C, 15N) isotopes as well as modelling (USLE/ RUSLE approaches). Qualitative assessment of off-site erosion impacts (sediment source attribution to water bodies) with compound specific isotope analysis.
  • Development of indicators for wetland degradation and regeneration using stable isotope patterns (13C, 15N) as well as molecular biomarkers
  • Mercury emissions from soils and ecosystems to the atmosphere.
