About me

I am a (Senior) Researcher at the University of Florence in the Probability group of Luca Avena (formerly of Francesca Nardi). In 2017 I obtained my PhD at Eindhoven University of Technology in the Stochastics group under the supervision of Johan van Leeuwaarden and Remco van der Hofstad. My research in applied probability is mainly focused on the fields of complex networks and mathematical physics.
