The Center for Comparative and International Studies (CIS) seeks to integrate the study of national political systems (comparative politics) and the study of international politics (international relations). CIS research and educational activities thus concentrate on the complex interconnections between domestic, international and transnational political processes, structures and institutions. The approaches used include formal theory, qualitative case studies, field and experimental research, statistical (econometric) methods and computational modeling. CIS activities focus on research, teaching and outreach.
