Biomarkers are organic molecules that occur in modern or ancient environments and can be traced back to a biological origin. We use various biomarkers to study biosphere-geosphere interactions.
Organic geochemistry helps to unravel how microorganisms catalyze, mediate and influence important reactions in geologic processes.
Biomarkers can be used to reconstruct paleo seasurface temperatures and land-sea-interactions.
We analyze trace concentrations of organic molecules in complex sample matrices with the help of dedicated procedures for sample preparation and state-of-the-art instrumentation for detection and identification.
