Kort presentation
Denna text finns inte på svenska, därför visas den engelska versionen.
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.
