The Public Law PhD Program is articulated in five different curricula: Constitutional Law, General Public Law and Comparative Public Law; Administrative law; Criminal law and procedure; International and European Union Law, and Law and Economics. The curriculum in Constitutional Law, General Public Law and Comparative Public Law deals with the classic issues of the disciplines, as defined by Italian and European public law doctrine. All the related topics to general, sectorial, state, and supranational legal systems; sources of law; fundamental rights, also within the multilevel European dimension; dynamics of territorial decentralization; constitutional guarantees and constitutional justice; government, also referred as relations among the supreme state institutions, local authorities and European Union Institutions. The curriculum in Administrative Law explores the transformation processes of the organization and functioning of public administrations and rule of law related issues as principle of legality and judicial protection of fundamental rights against public administration acts. The research topics move from the study of international administrations, in particular its coordination with national administrations, the analysis of specific issues such as food safety, environmental protection and competition. The curriculum in Criminal Law and Procedure proposes a didactic-training program in an attentive dimension oriented by an interdisciplinary framework of the criminal sciences, with the intention to stimulating doctoral students to a greater openness of their research, taking into account the interactions and influences with other disciplines such as prison law, criminology, forensic medicine and forensic psychology. The curriculum in Law and Economics promotes interdisciplinary legal and economic research activities, in order to improve the understanding of reasoning and effects of regulatory legal intervention, choices related to institutional arrangements and questions connected to the enforcement of legal regulation. The law is therefore therefore taken as an object of study, characterized by a set of behavioral incentives/disincentives, to be analyzed and studied through the use of economic instruments. The curriculum in International and European Union Law intends to offer advanced training in the field of transnational legal phenomena and its relationships with international law and European integration Law. PhD students will have to lead seminars and thematic debates in order to develop analytical and critical skills; activities that will be carried out in constant interaction with the other curricula of the phd program in order to improve the methodological perspectives of interdisciplinary nature.
