Biological systems are not only very complex, but also highly dynamic. The dynamic interactions between the metabolome and the proteome are of particular importance for the formation of the phenotype of biological systems. The exact chemical composition of a protein species defines its function, and virtually all biological processes are regulated by posttranslational modifications (PTMs) such as phosphorylation and acetylation.

Our research interests lie in the development of novel hyphenated mass spectrometric techniques for combinatorial time-resolved analysis of the proteo-metabolome and posttranslational modifications (Proteo-Metabo-Flux), functional proteo-metabolomics and fluxomics, spatial OMICs, as well as single-cell proteo-metabolomics to decipher molecular mechanisms at the interface of intermediary metabolism and modified protein species in context of systems biology, epigenetics and tuberous sclerosis complex (TSC) disease.

  • Functional Proteo-Metabolomics and Fluxomics: Development of hyphenated LC-MS techniques and bioinformatic approaches to study the regulatory interplay between cellular intermediary metabolism and modified protein species in metabolic and epigenetic regulation in the context of tuberous sclerosis complex (TSC) disease
  • Single-Cell Proteo-Metabolomics
  • Top-Down-Proteomics
  • Spatial Multi-OMICs
Key technologies
