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:
  • Ultracomplex mixtures: Identification of landscape-scale sources and transformation processes of natural organic matter (NOM).
  • Identification of transformation products of chemicals and their interactions with natural organic matter (NOM) in engineered and natural systems.
  • Non-target FT-ICR MS: Method development and use of stable isotopes in metabolomics and biogeochemistry.
  • Imaging mass spectrometry of biological systems: Uptake and distribution of chemicals, primary and secondary metabolites in plants and toxicology model systems.
  • Direct analysis of organic material on particles and solids by laser desorption/ionization.
