I am professor of Politics and International Relations at the School of International Relations at FGV. I conduct both academic research and practical work on nuclear security and nonproliferation, international security, climate politics, political violence, and the history and theory of international order, with a focus on Brazil, Latin America, and the Global South. In my engagement work, I collaborate widely with governments, international organizations, and think-tanks, including extensive consultation on nuclear and nonproliferation issues, to advance solutions based on applied social science. I am affiliated with the Reimagining World Order program at Princeton University, the Carnegie Endowment for International Peace, the Brazilian Center for International Relations (Cebri), and the Inter-American Dialogue in Washington DC, and maintain professional networks across Global South foreign and defense ministries.
