Research area: Microbial Networks

We are interested in a broad range of topics in quantitative microbiology, using both bacteria (E. coli, B. subtilis) and yeast (S. cerevisiae, S. pombe) as model systems. Our main focus is on quantitative analysis of the spatial organization and real-time functioning of cellular networks. To address these questions, we apply a range of fluorescence microscopy techniques, including FRET, super-resolution microscopy and automated imaging, combined with genomics, proteomics and computational modelling. We aim to elucidate properties that are common to most networks, such as capability to function robustly in a noisy environment, to integrate multiple extra- and intracellular cues, and to self-organize into large multi-protein complexes. We are also interested in combining theoretical and experimental approaches to better understanding the process of network evolution. Beyond individual cells, we investigate self-organization, signal exchange and gene regulation in multicellular microbial communities. Finally, we use our understanding of bacterial cellular networks to construct novel synthetic systems, from biosensors and artificial microbial communities to in-vitro reconstitution of essential cellular processes.
