His area of expertise lies in international politics with a focus on comparative regionalism. Currently, he is studying the role of regional organizations in coping with political crises within the context of a rise of illiberal democracies and electoral authoritarianism in the Americas and Europe. The project analyses the mechanisms through which regional organizations adopt and adapt global liberal norms of democracy and rule of law protection. Stefano is also interested in regional development policies, the political economy of regional development banks, and the politics of energy integration.
Stefano has been a research fellow at the Center for Latin American and Latino Studies at the American University (Washington, DC).
