About

I received my Ph.D. in Physics from the University of Montpellier in France, where I studied electromagnetic wave propagation in complex media, with an emphasis on nonlinear optical phenomena. I hold a M.Sc. degree in Science for Engineering from Sapienza University of Rome. I spent three years in Prof. David R. Smith's group at Duke Universityas as Postdoctoral Fellow first and as Research Scientist later.

Most of my research activity involves numerical modeling and investigation of electromagnetic propagation in complex media. In particular, nonlinear optical phenomena have constituted the principal subject of my studies, which required the employment of different numerical methods. My recent activity concerns nonlinear and nonlocal optical response of plasmonic nanostructures.
