Aree di ricerca: Elections and Political Parties, Political Behaviour, Public opinion


Lorenzo De Sio is Professor of Political Science at the LUISS Guido Carli University, Rome, where he teaches several courses at all levels. He is the director of the CISE research centre (Centro Italiano Studi Elettorali), and of the Master’s Programme in Governo, Amministrazione e Politica (GAP).

Formerly Visiting Research Fellow at UC Irvine, Jean Monnet Fellow at the Robert Schuman Centre of the European University Institute, Campbell National Fellow at Stanford University, he participated to several international research projects, among which “The True European Voter”(ESF-COST Action IS0806), the “EU Profiler” (2009) and euandi (2014) – both latter promoted by the EUDO Observatory on Public Opinion, Political Elites and the Media at the EUI’s Schuman Centre. A member of the ITANES (Italian National Election Studies), he recently conducted the Issue Competition Comparative Project (ICCP) international project.

His current research interests are mostly focused on quantitative analyses of voting behaviour and party competition in comparative perspective, with a specific focus on the role of issues in party strategy. He welcomes supervising MA and PhD students on these topics.

Among his publications, beyond several books and edited books in Italian and English, are articles appearing in the American Political Science Review, Comparative Political Studies, Electoral Studies, Party Politics, West European Politics, South European Society and Politics, and all major Italian political science journals.
