Our goal is to understand how stochasticity, non-linearity, correlations, and coupled excited state dynamics of biological systems and networks contribute to their function. We investigate these questions in different systems and at different levels, from the fundamental principles of protein and bio-molecular dynamics on the nanoscale to dynamic interactions in cellular networks, giving rise to physiological function. To address these questions, we adopt a multidisciplinary approach and develop new methods and technologies, such as advanced imaging and spectroscopy techniques based on ultrafast and quantum optics, and combine these with molecular biology, optogenetics, and electrophysiology.
