Metabolomics
Metabolomics, the latest of the so called “-omics” disciplines, offers a fascinating field for mass spectrometry based research. It makes use of system-wide approaches to investigate how phenotypes, visible as the set of metabolites, are influenced by defined (a) biotic perturbations. We mainly use LC-MS and GC-MS for the development of innovative metabolomics workflows. A special focus is put on the systematic use of stable isotope (13C, 15N, 34S)-assisted techniques to (1) facilitate the global assignment of the metabolome, (2) improve the accuracy of metabolome wide quantification, (3) chemical structure annotation and (4) the development of software tools for the automated processing of raw data.
Our research is carried out in close cooperation with partners from various disciplines such as computer science, molecular biology, mycology or plant pathology. We apply the developed methods to study the metabolomes and biological interactions of filamentous fungi, bacteria and plants.
