Research focus is the analysis of molecular dynamics in the context of biological or biomimetical systems; especially the analysis of molecular kinetics within supra-molecular complexes at the single molecule level. We employ state-of-the-art light microscopy techniques like confocal scanning microscopy and single-molecule microscopy using different illumination techniques. A further key aspect of our work is the development of new or the improvement of existing light microscopic methods; current emphases are light sheet fluorescence microscopy (LSFM), confocal LSFM, expansion microscopy and particle tracking.
