I am a permanent teacher of mathematics and physics at the Liceo Scientifico Avogadro in Rome. Currently on leave, I am a PhD student in physics at Sapienza and work at CREF under the supervision of Giulio Cimini and Vittorio Loreto. I deal with Opinion Dynamics and Social Networks models. Using statistical mechanics, the physics of Complex Networks and machine learning I try to understand how opinions change in networks, how networks in turn change depending on opinions and how an external observer can draw information from the data he collects.
