Research Interests

  • Feedback of global environmental changes on terrestrial ecosystems and biosphere-atmosphere-exchange of environmental important trace substances (N2O, NOx, CH4, CO2)
  • Measuring and mechanistic modelling of C and N turnover and associated matter fluxes in natural and managed ecosystems
  • (Further-) Development und Calibration of complex biogeochemical models by use of Bayesian methods, uncertainty assessment and uncertainty Quantification
  • Calculation of emission inventories of biogenic trace substances on regional and global scales



  • Lectures and tutorials in “Tropical Forests and Global Change” and „Biogeochemical Cycles and Bioshere-Atmosphere-Exchange“ at the Faculty of Forest and Environmental Sciences, Albert-Ludwigs-University Freiburg.
  • Lecturer at „Summer School on Biosphere-Atmosphere Exchange of Radiative Active Trace Gases, Xishuangbanna, China.
  • Lecturer at Summer School „Methods to study microbial nitrogen turnover and the formation of greenhouse gases.
