My research focuses on the detailed understanding of greenhouse gas (GHG) exchange in ecosystems worldwide, including wetlands, woodlands, forests, savannas, grasslands and livestock systems.

By applying micrometeorological methods such as the eddy covariance technique I aim to define major meteorological as well as biological factors influencing ecosystem GHG exchange and link the biogeochemical cycles of carbon, nitrogen and water.

Besides studying the ecosystem scale, I am further interested in exchange of GHGs at the process level (leafs, soils and animals using GHG chambers) and larger scales (regional to global) using modeling (empirical, semi-empirical and process-based biogeochemical models) and remote sensing approaches, while linking environmental aspects to productivity.

Beyond the quantification of GHG exchange I am driven by a simple question: “How do ecosystems function now and how will they function in the future?”

In addition to fundamental research I am motivated to educate undergraduate and graduate students in environmental sciences but also to apply recent research findings in the real world e.g. by doing environmental assessments of agricultural production systems in developing countries.
