Leyla Tiglay is a PhD student at Ohio State University focusing on the international history of the Cold War and decolonization. She is an interdisciplinary scholar trained in political science and history. Her dissertation examines French nuclear policies from the late 1940s to the 1960s. The project explores the nexus of the French nuclear program with the history of decolonization in Africa and the Middle East, the history of nuclear scientific networks, and the international history of nuclear disarmament. Franco-American relations are also a major background theme of her research. Tiglay aims to contribute to major discussions on nuclear proliferation and disarmament with fresh cross-disciplinary insights from the historical case study of the French nuclearization.
