Research focus

• Investigating the atmospheric CH₃Cl-budget using a Large Volume Air Sampling System (LVASS) to determine stable isotopic compositions (δ²H, δ¹³C, δ³⁷Cl) of atmospheric CH₃Cl at several locations in Southern Germany
• Assessing the role of microorganisms in CH₃Cl-cycling in the marine environment employing stable isotope techniques
• Tracing emission and degradation processes of CH₃Cl by plants and phyllosphere microorganisms under natural conditions (in-vivo) vs. laboratory conditions (incubation experiments) using GC-MS, GC-IRMS and CRDS
• Exploring the close relationship between the biomass-CO₂-cycle and CH₄-cycle in plants and the phyllosphere, using stable isotope techniques and microbiological methods
