All students are required to produce and defend a thesis on a topic falling within the scope of their study programme. The thesis can be written in English or French, the language having been chosen in agreement with the supervisor of the thesis. The thesis is the product of individual research and allows students to deepen their knowledge and understanding of a specific topic.

To valorize the research work done by the students in the Master of Arts in European Interdisciplinary Studies, the best Master's theses might be published in prominent outlets.
