I work at the  University of Siena, where I studied during the Eighties of the XX century and where I came back in 2001, after my first experience as an assistant professor at the University of Bologna. I have been appointed associate professor and then full professor (2007) at the faculty of Political Sciences of the University of Siena. In 2009 I have been appointed Dean of the Faculty. Currently, I am serving as a member of the Administration Board of unisi.
My research is based at the Department of Social, Political and Cognitive Studies, and within a smaller community of social scientists: the CIRCaP (Centrer for the Study of Political Change). At the CIRCaP’s web, you can get information about our projects and check the news. At the CIRCaP, over the years, we have started a Graduate School in Political Science, offering graduate programs in political science. The Unisi Ph.D. program in Comparative and European Politics has now merged into a larger Ph.D. School in Political Science, in cooperation with the Universities of Florence and Bologna and the Scuola Normale Superiore (SNS) of Pisa.
I have been working for years, with different responsibilities, at the Rivista Italiana di Scienza Politica, the journal founded by Giovanni Sartori, which has been the main locus of dissemination of political science in Italy. I have been a member of editorial board and, between 2010 and 2013, the Editor in chief. Currently, I serve as co-Director of the Rivista Italiana di Politiche Pubbliche and I am a member of the Editorial board of South European Society and Politics and The Journal of Legislative Studies.

Among the research programmes I participated in the past, I would mention the integrated Network  Intune, funded by the VI Framework Programme of the EU, ed il research project on the Italian Parliament funded by the Italian Ministry for Education and University. I am a member of the European Standing Group on Legislative Studies and of the Research Committee on Elite Studies of the International Political Science Association. Moreover, I am among the founders of the network Selection and Deselection of Political Elites., 
The main reference for the Italian political science is the SISP (Società Italiana di Scienza Politica). In the past, I served as organizing secretary of the association. At the European level, the most relevant association is the European Consortium for Political Research (ECPR). I am currently a member of the ECPR Executive Committee and I have the responsibility of the annual Research Session.
