My research focuses on understanding multicellularity, motility and nitrogen fixation in cyanobacteria. I investigate the formation of heterocysts, specialised cells for nitrogen fixation, their connection to photosynthesis and the exchange of metabolites and regulators with neighbouring C-fixing vegetative cells. Methods include confocal microscopy, electron microscopy, fluorescence spectroscopy and molecular biology.
