Fabio Saracco has a Master's Degree in Theoretical Physics at the University of Florence, with a thesis on non-linear Cosmological perturbations; he obtained his Ph.D. in Theoretical Physics (String Theory) at the University of Milano Bicocca in 2013, with a thesis on the resolution of strings singularities with Alessandro Tomasiello (INFN, Milano Bicocca department; Physics Department, University of Milano Bicocca). In 2013 he took an interest in the Complex Systems research: at the Institute for Complex Systems (ISC-CNR, Sapienza Department, Rome), he worked on Economic Complexity, a brand new branch of economic analysis able to measure the productivity capabilities of different countries. In this period, Fabio, in collaboration with Riccardo Di Clemente (ISC-CNR; MIT, Boston), Andrea Gabrielli (ISC-CNR, IMT) and Tiziano Squartini (ISC-CNR; IMT), developed a completely analytical method of network randomization for the special class of bipartite networks, with direct applications in Economic Complexity. Since October 2015, Fabio joined the NETWORKS research unit at IMT, with Guido Caldarelli. Fabio recent objects of research run from dynamical evolving network, non-linear algorithms and complex network null-models; the applications of these methods mostly cover the Trade Webs, but recently have been enlarged to other subjects, like Biological systems and Social networks.

Mark Buchanan PhD, is an American physicist and author. He was formerly an editor with the international journal of science Nature, and the popular science magazine New Scientist. He has been a guest columnist for the New York Times, and currently writes a monthly column for the journal Nature Physics. Buchanan's books and articles typically explore ideas of modern physics, especially in quantum theory or condensed matter physics, with an emphasis on efforts to use novel concepts from physics to understand patterns and dynamics elsewhere, especially in biology or in the human social sciences. Key themes include, but are not limited to the (often overlooked) importance of spontaneous order or self-organization in collective, complex systems. All of his work aims to bring technical advances in modern science to a broad, non-technical audience, and to help stimulate the flow of ideas across disciplinary boundaries. He has been awarded, in June 2009, the Lagrange Prize in Turin, regarding science writing in the field of complexity.

Andrea Gabrielli PhD, is a theoretical physicist. In recent years he collaborated to the development of the theory of Economic Complexity and studied the problem of reconstruction of complex networks from partial information which is of capital importance mainly in finance.

He is currently a researcher at CNR and  Visiting Professor at Institute for Advanced Studies (Lucca, Italy),  and at the Physics Department of the Boston University (MA, USA). He is the author of around 100 scientific publications on peer reviewing international journals and of one scientific book of statistical physics published by Springer (2004).
