In our research group we are investigating the (re-)cycling of nutrients in terrestrial ecosystems, which occurs in the soil-plant-microbe system. Our main focuses are on the gross soil dynamics of nitrogen and phosphorus, as well as the production of biogenic greenhouse gases. We are interested in how global change (climate and land use) affects nutrient cycling and how those feedback to the change, e.g. by governing the responses of vegetation or by production of greenhouse gases.
We are applying a range of methodologies for studying biogeochemical cycles. Stable and radio- isotope techniques are powerful tools to study gross nutrient dynamics and to investigate production pathways of biogenic greenhouse gases. We are also interested in identifying which microbial groups are the main drivers of biogeochemistry in soils.
