Academic and professional background

- PhD, Department of Environmental Science, ETH Zurich, Switzerland (2014)
My research focuses on the biogeochemistry of phosphorus and nitrogen in terrestrial ecosystems, with a special emphasis on soils. I am particularly interested in understanding how biogeochemical processes in soils change along environmental gradients. For this purpose, I often use stable isotopes as a tool to characterize and trace such processes, both, in controlled laboratory settings and in the ostensible chaos of environmental systems.

- The Effect of Land-Use Change on Soil Nutrient Pools in Sub-Saharan Africa
- Biogeochemical Cycling of Phosphorus and Nitrogen along Riparian Buffer Zones
