The Research Committee investigates all issues related to the process of European integration and EU politics. This comprises inter alia theories of integration, public policy in the EU, multilevel governance, EU legitimacy and democracy, etc. Necessarily, the group keeps a pluralistic epistemological and methodological attitude and contributions from different approaches are always welcome. A basic tenet of the RC03 is that the study of EU integration, policies and politics can be approached from the conceptual, methodological and epistemological tools provided by political science sub-disciplines, such as comparative politics or political theory. This presupposes an open attitude to cooperate with other IPSA RCs. Moreover, the study of regional integration is not a phenomenon limited to Europe: similar processes can be identified elsewhere and, because of this, the RC stimulates engaging with comparative regionalism.
