Alessandro Vespignani received his undergraduate degree and Ph.D., both in physics and both from the University of Rome "La Sapienza", in 1990 and 1994 respectively. After holding research positions at Yale University and Leiden University, he has been a member of the condensed matter research group at the International Center for Theoretical Physics (UNESCO) in Trieste. Before joining Indiana University,Vespignani has been a faculty of the Laboratoire de Physique Theorique at the University of Paris-Sud working for the French National Council for Scientific Research (CNRS).
Vespignani has worked in a number of areas of non-equilibrium particle systems, statistical physics and computational sciences, including characterization of non-equilibrium phase transitions, fractal growth and self-organized criticality. Recently Vespignani's research activity focuses on the interdisciplinary application of statistical and numerical simulation methods in the analysis of epidemic and spreading phenomena and the study of biological, social and technological networks. For several years he has been working on the characterization and modeling of the Internet, the WWW and large-scale information networks. He is now focusing his research activity in modeling the spatial spread of epidemics, including the realistic and data-driven computational modeling of emerging infectious diseases, the resilience of complex networks and the behavior of techno-social systems.
Vespignani has published 120+ peer reviewed papers in top rated scientific journals, including Nature, Science and PNAS that have accrued more than 7,000 citations. He is author, together with Romualdo Pastor-Satorras, of the book Evolution and Structure of the Internet. Together with Alain Barrat and Marc Barthelemy he has published in 2008 the monograph Dynamical Processes on Complex Networks. Vespignani is an elected fellow of the American Physical Society and is serving in the board/leadership of a variety of professional association and journals and the Institute for Scientific Interchange Foundation in Turin, Italy.


This talk will focus on the study of "techno-social" systems, where infrastructures composed of different technological layers are interoperating within the social component that drives their use and development. In this context we aim at understanding how the very same elements assembled in large number can give rise to different macroscopic and dynamical behaviors, opening the path to quantitative computational approaches and forecasting power.
