Short presentation
My research is focused on the study of functional materials using sychrotron radiation based spectroscopic techniques. My main focus is in on the charge dynamics in hybrid- and inorganic perovskite materials, and molecular systems using different time-resolved spectroscopies. Other activities include Auger- Photoelectron Coincidence Spectroscopy (APECS) on functional materials and molecular systems for catalysis.
