My research is embedded in the DFG joint research program SoilSystems (https://soilsystems.net/) that aims to integrate thermodynamic descriptions into the processes of soil organic carbon turnover in order to gain a systemic view on energy and matter fluxes and their relations to biota, non-living soil components, and environmental properties as boundary conditions. This will enable improved assessment and prediction of dynamic biogeochemical processes, boundary constraints and performance limits.
Furthermore, I am particularly interested to investigate the turnover and stabilization mechanisms of soil organic matter in forest ecosystems under the influence of tree species using biogeochemical methods. Beyond the research area of soil organic matter, my second research focus is on the genesis and development of soils in different landscapes as well as their classification according to the German classification system and the World Reference Base for Soil Resources (WRB).

I gave several practical courses at the University of Trier that encompass field courses in soil science (incl. genesis, identification, classification and mapping of soils) as well as lab courses to characterize soils using different biogeochemical methods.
