For the third consecutive year, École Polytechnique hosted Opération CIEDS, an annual event dedicated to research and innovation in defense and security. The event, organized by the Center for Defense and Security Studies (CIEDS), in which many of the École Polytechnique's research laboratories are involved, is supported by the Ministry of the Armed Forces and the Defense Innovation Agency.
About 15 Bachelor's students got together under the guidance of Guillaume Dubach, Monge professor at École Polytechnique and member of the Laurent Schwartz Mathematics Center (CMLS), for two weeks of intro to math research in a summery, relaxed setting. This initiative was supported by École Polytechnique's “Pedagogy Dynamics” fund, financed by École Polytechnique Foundation.
Alain Aspect, a former student of the ENS-Cachan (now ENS-Paris-Saclay), professor at the Institut d'optique-université Paris-Saclay, professor at École polytechnique, and emeritus research director at the CNRS, was elected to the French Academy on June 26, 2025. He thus becomes the second French Nobel Prize winner in physics to be elected to the French Academy after Louis de Broglie, who won the Nobel Prize in 1929 and was elected in 1944.
Three student teams from École Polytechnique’s Master's program STEEM (Energy Environment: Science, Technology & Management) participated in the international competition EuroTeQaThon 2025, which was organized at Eindhoven University of Technology from June 14 to 16, 2025. The event brought together over twenty teams of students from the EuroTeQ Engineering University alliance, of which École Polytechnique is a member.
The Institut Polytechnique de Paris, of which École Polytechnique is a founding member, is ranked 41st worldwide and 2nd in France in the QS 2026 ranking of world universities. The QS ranking covers 1,500 universities in 106 higher education systems.
