Activities

I was born in 1983 in Siena, where I graduated in 2008 with a Master's Degree in Physics and defended my PhD thesis ("Information-theoretic approach to the analysis of complex networks") in 2011. During the biennium 2012-2013 I was Postdoctoral Researcher at the Lorentz-Institute for Theoretical Physics (Leiden, NL) under the supervision of Diego Garlaschelli. From January 2014 to October 2015 I was Postodoctoral Researcher at the Institute for Complex Systems UOS Sapienza in Rome. The results of my research were published on several journals, including high-quality peer-reviewed ones (Phys. Rev. Lett., Sci. Rep., New J. Phys., Phys. Rev. E, J. Econ. Interact. Coord.). I have participated to international conferences both as invited and contributed speaker and collaborated with professors working in Economics and Finance (as Dr. Iman van Lelyveld, working at the Supervisory Policy Division of the Dutch National Bank and Prof. Giorgio Fagiolo, professor of Economics at Sant'Anna School of Advanced Studies). I left the PIL group at ISC (where I worked under the supervision of Luciano Pietronero and Andrea Gabrielli) to move to IMT Institute for Advanced Studies, in Lucca where I am currently working as an Assistant Professor.

Research interests: economic complexity, econophysics, complex networks, statistical mechanics of networks, neural networks
