Forschungsgruppe Metabolische Interaktionen

Die Inhalte dieser Seite sind leider nicht auf Deutsch verfügbar.

We use modern mass-spectrometry methods to understand which molecules are involved in marine host-microbe systems, how different metabolites shape ecological communities, and how the symbiotic partners respond metabolically to environmental changes.

The research in this lab is constantly driven by method developments like high-resolution mass-spectrometry imaging to reveal the spatial metabolome of microbial systems. Our expertise is microbial metabolomics with a special focus on marine systems.
