Member of Project 3.1 "Dynamics of Condensed Phase Molecular Systems"

Research

My main scientific interest is in the ultrafast molecular dynamics in solution - I investigate how a molecule evolves after absorption of a photon. Thus, the basic idea is to watch a molecule during photophysical or photochemical reaction. In particular, I am interested in the photophysics of DNA. DNA safely stores our genetic code. "Safely" is the keyword in the previous sentence - because DNA is surprisingly photostable - which is obviously a prerequisit for the development of life on earth. The mechanism behind this photostability is still not understood. There are different routes to approach this problem: from studying the photoresponse of the individual building blocks in vacuum to the investigation of living cells. Here, we use the bottom-up principle, i. e. we start from the small individual building blocks and slowly increase the complexity of the system. In addition, we study these system in aqueous environment. Our method of choice is time-resolved photoelectron spectroscopy in solution. This technique in principle allows us to follow the molecular dynamics in energy and time, and to identify all transient states involved.
