Research Interests

I am interested in the study of ultrafast processes as charge carrier relaxation, exciton cooling, Auger recombination and multiple exciton generation in perovskites materials (colloidal 2D nanostructures and thin films) using femto-second Transient Absorption Spectroscopy (fs-TA) and Time-resolved Photoluminescence (TR-PL).
