Single molecule methods are essential for gaining a thorough understanding of complex biological processes. This approach allows real time observation of signalling processes and of molecular machines at work. We use a variety of methods based on single molecule fluorescence and Förster Resonance Energy Transfer (FRET) to address dynamics on a wide timescale from less than a microsecond to several minutes. This is necessary for example for understanding how binding of small molecules (performed in less than a millisecond) can result in large conformational changes (taking up to seconds) and finally to regulation of protein expression levels in a cell.

The multidisciplinary nature of our research requires close collaboration with many colleagues in the fields of biology, biochemistry, medicine, biotechnology and physics.
