During my PhD in Physics (Università di Modena e Reggio Emilia) I have installed, calibrated and validated the X-Ray Photoelectron Spectroscopy (XPS) facility at ISOF.
Currently I manage the XPS surface chemistry analysis facility, I am responsible for the scientific activity and technical maintenance. I am in charge of the electrical characterization of Graphene-based composites and devices insiede the Graphene Faghship project.
My research activity is mainly focused on XPS characterization of Carbon based materials. I am interest in chemical functionalization of aromatic carbon of 2D materials.
I have published an innovative approach on XPS data analysis focused on quantification of the oxygen content in Graphene Based Materials indipendently from thickness and substratess. PhD thesis link
