Molecular Biogeochemistry



The research group explores key processes in the global biogeochemical cycles at the molecular level. Biomarkers and their isotopic content hold information on the regulation of the individual processes. The group is developing new tools and is applying existing techniques to investigate single key processes.

Interested in working with us?

We are always looking for interested students who want to pursue a Masters Thesis (preferably in combination with a project module) with us. More information about open positions:
