Ultrafast Spectroscopy and Attosecond Science

We investigate the dynamics of molecules on their natural time scales of femtoseconds (1 fs=10-15s) to attoseconds (1 as=10-18s). The central interest of our research is the characterization of the electronic structure and dynamics of the valence shell of molecules. We develop new methods to characterize the evolving electronic structure of a molecule undergoing a chemical reaction on the femtosecond time scale and to measure electronic dynamics on the attosecond time scale.
