I am interested in how changes in biodiversity and environmental conditions (atmospheric carbon dioxide, temperature, precipitation) affect plant-soil interactions, with a particular focus on plant litter and decomposer organisms. The main research goal is a mechanistic understanding of the drivers of biogeochemical cycles using experimental approaches in the field (alpine, temperate, Mediterranean and tropical forest ecosystems) and the laboratory.
