The research group BioGeoOmics integrates state-of-the art instrumental and methodological approaches to study dynamic interactions of molecules in the environment. These molecular interactions include natural processes (e.g. metabolism, organic matter diagenesis) as well as anthropogenic interferences (interaction of biological systems with chemicals).

At the core of the the analytical toolkit of the BioGeoOmics-group, we use ultra-high resolution mass spectrometry (FT-ICR MS) and mass spectrometric imaging (MSI) supported by biogeochemical and chemo-informatics methods. We use these tools to explore chemical and biological transformations of organic molecules, their spatial localization in tissues, and to identify metabolites and unknown chemicals and transformation products in complex mixtures.

The methods and concepts are applied to various research fields:
  • Ultra-complex mixtures: Natural organic matter characterization and transformation
     
  • Identification of transformation products and their interactions in complex mixtures
     
  • Non-target analysis: Applications of stable isotope metabolomics (NT-SIM) and biogeochemistry (NT-SIB) with use of FT-ICR MS
     
  • MSI of biological systems: Uptake and distribution of chemicals, primary and secondary metabolites in plants and zebrafish model systems
     
  • Single-cell metabolomics/fluxomics
