Research Area

Our research goal is to uncover the regulatory network that controls metabolism. This network is largely unexplored compared to the well-mapped stoichiometry of metabolism. A major barrier is that we don’t know which of the many metabolites in a cell interact with enzymes and regulatory proteins, and that we don’t understand the regulatory role of these interactions. To address these problems, our group combines molecular biology methods (e.g. CRISPR perturbations), multi-omics analysis and computational methods. Metabolomics methods are especially important, and we develop methods for measuring hundreds of metabolites using state-of-the-art mass spectrometry technology.

SYNMIKRO Young Researchers Groups

Almost all scientific members of SYNMIKRO are actively involved in DFG’s Collaborative Research Centers (Sonderforschungsbereiche), Research Training Groups (Graduiertenkollegs), or other Cooperative Research projects. Alongside performing adventurous experiments, and reporting excellent science, SYNMIKRO substantially promotes potential Young Research Group Leaders by constantly keeping its doors open to welcome and support Young Researchers planning to set up an Independent Research Group.
