Spectroscopy and coherent control in biological systems
Staff
We develop and apply spectroscopic techniques based on femtosecond lasers in order to shed light on structural dynamics of proteins during biochemical processes. The association of mid-infrared femtosecond pulses with state-of-the-art femtosecond technologies such as pulse shaping and multidimensional spectroscopy offer a powerful tool to investigate biomolecules such as hemoproteins.
