The molecular geobiology group at Kiel University studies organic molecules in modern and ancient microbes. We combine expertise from organic (bio)geochemistry, geomicrobiology, and molecular biology to study how and why microbes produce organic molecules (such as lipids, pigments, and co-factors) and to learn what the rock record of these molecules can tell us about earth’s climatic and geochemical evolution. Our main analytical tools are lipidomics via liquid chromatography-mass spectrometry, compound-specific stable isotope analysis, experimental microbiology, and phylogenetic analyses.
We just launched the HYDROCARB project, which is funded by the DFG through the Emmy Noether program. Within the project we aim to develop novel paleoclimate proxies based on the carbon and hydrogen isotopic compositions of archaeal lipids. Check out our Projects page for more information. PhD and postdoctoral position will become available soon and will be posted on the website.
