Research Areas

The current research interests include: the electronic state spectroscopy of biomolecules, aeronomic and plasma processing molecules by interaction with photons (VUV photoabsorption, REMPI, He(I) photoelectron) and electrons (dissociative electron attachment, electron energy loss); charge transfer processes in atom-molecule and anion-molecule collisions and the role of negative ions; surface induced chemistry, especially the reactivity of co-adsorbed molecular species and the formation of ices in the Earth’s upper atmosphere and in the interstellar medium, that might be in the origin of some microorganisms. Charge transfer experiments in atom-(bio)molecule collisions with negative ion formation. Other research interests include positron scattering from atoms and molecules as well as positronium formation.
