Main Research Interests

I study biogeochemical cycles in soils of near-natural ecosystems, including plant-soil-microbe interactions in the rhizosphere. Based on an improved understanding of these processes, I assess different soil functions and their sensitivity to effects caused by changes in climate and land use management. The most recent studies focus on the interaction of soil moisture regimes, e.g. drying and rewetting cycles, with the availability and leaching of nutrients and the emission of greenhouse gases (CO2, N2O, CH4).

For details on processes at the interface between plant root and soil see research focus "Rhizosphere".

Bachelor and Master Theses

Digit Soil - A rapid measurement of soil health (M.Sc. thesis project)

According to FAO (Food and Agriculture Organization of the United Nations), a quarter of the global surface of agricultural land is already highly degraded, therefore maintaining long-term soil health gains importance. Nevertheless, there are currently no easy, fast, and reliable ways to assess the effects of soil management on soil health and in particular on soil biology.
The planned Thesis-project seeks to support development of an easy-to-use, portable sensor (Digit Soil), measuring the activity of soil enzymes as a soil health indicator.

Starting date: any time 2021 or beginning of 2022
