As a scholar of international security, his work examines how states, institutions, and societies navigate the evolving landscape of global security governance. His research is organized around three main lines of inquiry.

Nuclear governance, nonproliferation, and deterrence
A central focus of his scholarship is the evolution and contestation of the global nuclear order. He has written extensively on the politics of the Nuclear Non-Proliferation Treaty (NPT), nuclear sharing in Europe, the dynamics of treaty negotiations, and the behavior of both established and emerging powers within nuclear institutions. His recent work also explores how geopolitical shocks—such as Russia’s invasion of Ukraine—reshape national strategies and public attitudes toward deterrence, nuclear risk, and disarmament.
