My research is focussed on fundamental studies of the interaction of small quantum systems (such as molecules, multimers of biomolecules, small clusters) with light -- x-rays and ionizing UV radiation.The ultrafast processes that occur in the femtosecond-scale following the absorption of energy are the key for understanding many phenomena such as radiation damage in DNA and other biomolecules, light-activated processes (such as vision or many catalytic processes) but also the action and efficiency of radiosensitizing agents in cancer therapy.
Our research is based on advanced spectroscopic methods such as multiparticle coincidence spectroscopy, actively utilizing large international infrastructures: SACLA free-electron laser in Japan, EuXFEL in Germany, MAX-IV synchrotron in Sweden. We are also active in designing and building new instruments for these facilities. The research is carried out withing the framework of large international collaborations, closely involving also theoretical calculations and modeling.
