The Fiebig research group is interested in a fundamental understanding of molecular interactions and ultrafast processes (e.g. energy, electron and proton transfer) in complex molecular architectures. Our primary focus is to develop and apply new spectroscopic methodologies for probing real-time structural changes in biological systems. The underlying goal is to understand molecular function by probing structure and dynamics simultaneously. Currently, the Fiebig group investigates the interaction of UV-radiation with DNA on the ultrafast time scale addressing the question of how electronic excess energy delocalizes and dissipates in π-stacked nucleic acids.
