Function and Responsibilities:

• Head of Earth-Atmosphere Interactions (TEAM)
• Speaker of TERENO Observatory Northeast German Lowlands
• Elected member of the Internal Scientific Council of GFZ
  

Research Interests:

With my group I investigate processes and drivers underlying (changes in) the geosphere-atmosphere exchange of heat, water vapor, and carbon on a range of temporal (hourly to multi-annual) and spatial (local to continental) scales. We do so by combining ground-based and airborne micro-meteorological measurements, biogeochemical analyses, airborne and satellite remote sensing, numerical simulations, and machine learning methods. The current focus is on heavily disturbed and very dynamic peatland systems in NE Germany and pristine Arctic permafrost ecosystems with the aim to quantify changes in atmospheric composition and radiative forcing resulting from Earth surface processes.
