Andrea Rapisarda is Associate Professor of Theoretical Physics at the Department of Physics and Astronomy of  Catania University, Associate Research Scientist of INFN (Italian National Institute for Nuclear Physics), Codirector of the Lipari School on Complex Systems and Member of the Editorial Board of Physica A.  His main research interests are statistical mechanics and complex systems. In the last years, he started to work on applications of mathematical and computational models to social and economic systems,  demonstrating how the application of random strategies  in a hierarchical organization allows, under certain conditions, to circumvent the so-called "Peter Principle" and to improve the  efficiency of the organization. This interdisciplinary research received much attention by  the international community (see link) and was also awarded with the 2010 Ig Nobel prize for Management at Harvard University (USA). Recently, considering a model of a Parliament,  he showed how  the introduction  of a given percentage of common citizens, selected by lot and independent from the political parties, allows to increase the efficiency of the parliament itself, in terms of both approved laws and "social welfare". This study has also  stimulated a wide international interest (see link
