With a PhD in Sociology, his main research interests concern the integration of the immigrant population, with particular reference to employment and migration policies. In recent years his research work has been focused on the combination of European Union entry policies and on regional integration in the Mediterranean basin. In the first instance, his investigations have concerned the effects of the response given by the countries of the European Union to the need to manage migration in the development and intensification of regional integration processes in the Mediterranean. Alongside the social and political analysis of immigration, he has also addressed Italian emigration and emigration policies. His analysis has also been conducted according to the historical sociology methodologies.
