Sanne Cornelia J. Verschuren is a Marie Curie Postdoctoral Fellow at the Center for International Studies of Sciences Po. Her research interests include the development of military technology, shifts in military strategy and tactics, and the role of ideas and norms therein. Her book project examines why and how states decide to procure different weapon capabilities within similar domains of warfare. More specifically, she seeks to understand the politics behind the development and operationalization of military aircraft (1920s–1930s), aircraft carriers (1950s–1960s), and missile defenses (1980s–present) in the United States, the United Kingdom, France, and India. Sanne's dissertation, which serves as the basis for her book, won the 2022 Kenneth Waltz Outstanding Dissertation Award from APSA's International Security Section. Beyond the book project, Sanne works on questions around the global arms trade, the politics of deterrence, and the intersection of nuclear and conventional capabilities. Before joining Sciences Po, Sanne was a postdoctoral fellow with the Center for International Security and Cooperation at Stanford University and a predoctoral research fellow with the Harvard Kennedy School’s Belfer Center for Science and International Affairs. Sanne’s research has been supported by the European Commission, the National Science Foundation, the Horowitz Foundation for Social Policy, and the Belgian American Education Foundation, among others. Sanne received her Ph.D. in Political Science from Brown University in August 2021.
