I am mainly working on the fate of organic matter (C and N cycling) in soils, from the plant input via roots and decaying litter in rhizosphere and detritusphere over microbial transformations to particulate and mineral-associated soil organic matter. I increasingly focus my work on the formation of soil structure as affected by the organic matter allocation in the rhizosphere, the soil volume directly influenced by root activity. A special interest of work relates to soil functioning in pristine polar environments in the Arctic (C storage in Cryosols) and in Antarctica (nutrient and water availability) and soil structure development under different climate in Chile. In my research I combine quantitative approaches (e.g. density fractionation, elemental and isotopic analyses, lab incubations) with state of the art chemical (GC-MS, NMR spectroscopy) and spectromicroscopic (SEM, NanoSIMS) techniques.
