Daniele Caramani's research is broadly comparative. It has a strong historical dimension with time series reaching back to the first phases of democratic transition, state building, and industrialization up to the present day. Empirical research is based on comparative and quantitative-statistical methods, and has produced documented datasets and archives which are available to the academic community. It includes work on elections and representation, electoral systems and electoral behaviour, parties and party systems, democratization, state formation and nation-building, methodology, European integration, globalization, regionalism and nationalism, and political geography. His main contribution has been in the field of the theory of the nationalization and Europeanization of politics. Currently, he works on extending that research with a third monograph on the "globalization" of politics. Further projects include work on technocracy, populism, left-right in global perspective and global voting rights.
