Master in International Security

Section #objectives

General objectives

This Master in International Security at PSIA trains students to develop the tools and knowledge they need to effectively understand and analyse issues in the international security field in the 21st century, including : changes in the international environment (remodelling of geopolitical systems, new forms of crises and conflicts, controversial military interventions, transnational terrorism, nuclear proliferation, cyberwarfare, etc.), conflict-ridden regions and the specific internal transformations in security and defence activities (specialisation, institutional transformation, "judicialisation", new technologies, etc.)

Section #eligibility

Main orientations and specific features

The curriculum for International Security is divided into three academic semesters and one semester dedicated to a professional internship or an exchange study program at a partner university.

Students study Master core courses relating to the major themes of the international security field, including:, strategy, defence economics, war and crises, peace, development and diplomacy.

Additionally, students must choose two concentrations from 12 thematic and 5 regional concentrations.

The program enjoys close collaboration with French defence institutions, notably the Saint-Cyr-Coetquidan military school and the École de Guerre allowing students to familiarise themselves with the existing articulations between public and private decision making in the fields of defence and security. This collaboration also allows them to acquire the theoretical and technical knowledge related to political-military relationships.

PSIA’s Pedagogical Committee approved an amended degree structure for students starting PSIA degree programs in September 2020. Further details regarding PSIA’s general program structure.

Section #Scientific Advisor

Scientific advisor

Professor Benoît Pelopidas is the founding director of the Nuclear Knowledges program (formerly chair of excellence in security studies) at Sciences Po (CERI). His program, “Nuclear Knowledges”, is the first independent scholarly research program on the nuclear phenomenon in France. He is also an affiliate of the Center for International Security and Cooperation (CISAC) at Stanford University. His research has received four international prizes and the most prestigious European grants based on scholarly assessment by peers, most notably an ERC Starting Grant.

This interdisciplinary effort of independent scholarship has led to the following discoveries over the last five years: the lack of credibility and rationality of the French nuclear arsenal at least until 1974; the underestimation of the effects of French nuclear weapons tests in Polynesia; the role of luck in the past avoidance of unwanted nuclear explosions; the limits of popular support for nuclear weapons policy and the role of nostalgia and imagined futures in shaping nuclear weapons politics.
