Welcome to the homepage of the Microbial photosynthesis group

The research objectives of our group are focused mainly on photosynthetic processes in cyanobacteria and other microalgae on a scale ranging from molecular mechanisms to biogeochemical implications.

At the subcellular level we rely heavily on fluorescence microscopy to investigate the mobility of photosynthetic proteins and their organization within the thylakoid membrane.

Furthermore, our research extends to the physiology of phototrophs at a single-cell level, such as the role of cell-to-cell heterogeneity in N2-fixing cyanobacteria.

Another key interest of our group is how environmental factors such as light and nutrient availability regulate photosynthetic processes and photoprotective mechanisms at the population level.
