Interview with Margherita Castellano, a doctoral student at the Center for Applied Mathematics (CMAP), who has qualified for the national finals of the science communication competition “My Thesis in 180 Seconds" (MT180*). She is seeking to better understand the role played by small molecules called surfactants when two immiscible fluids interact, as in the case of air and water in soap bubbles.
X2019, Amaury Lancelin is conducting his doctoral research at the Dynamic Meteorology Laboratory (LMD*), in partnership with RTE (Réseau de transport d’électricité). The goal is to improve the study of heat waves, cold waves, intense precipitation, and other extreme weather events.
With more than 230 start-ups supported over the past ten years, École Polytechnique and its incubator, X-UP, are contributing to the growth of European entrepreneurship. Interdisciplinary research centres, support services, the X-FAB prototyping facility and the presence of entrepreneurs in the business incubator make the École Polytechnique’s Center for Entrepreneurship and Innovation a unique environment that fosters creativity. Project leaders – whether they are students or researchers from École Polytechnique, other institutions within the Institut polytechnique de Paris, or from further afield – will find this the ideal place to bring their ideas to life.
On Saturday 11 April, almost 350 secondary school girls from the Île-de-France region were welcomed to the École Polytechnique campus. There, they had the opportunity to learn about scientific study programmes and careers in various fields, such as aeronautics, defence, artificial intelligence, energy and the environment, and research, from 47 female professionals and 15 students. They also had the opportunity to meet Elisabeth Borne, the former Prime Minister (who was the second woman to hold this position under the Fifth Republic), and Laura Chaubard, President and Chief executive of the École Polytechnique.
Scientists from the LHCb experiment at CERN, including a team from the Leprince-Ringuet Laboratory (LLR*), gathered for a workshop at École Polytechnique to discuss how to improve the LHCb particle physics experiment over the next decade.
At the 2026 ‘AI for Impact’ Spring School, École Polytechnique’s ‘Data Science & Industrial Processes’ Chair is reaffirming its role as a bridge between cutting-edge research and the business world. By bringing together students, scientists and businesses from around the world in Morocco, the event demonstrates the ability of data science and artificial intelligence to unite talent, innovation and practical applications in the service of major industrial and societal challenges.
On 13 and 14 March, 400 secondary school pupils set their sights on the stars at the École Polytechnique campus as part of the RocketriX challenge, organised by the school's Equal Opportunities Unit and the AstronautiX student society.
Against a backdrop of rising geopolitical tensions, six second-year Cycle Ingénieur Polytechnicien students participated in the British Model NATO, held on February 25 at the British Foreign Office. This first French participation in the British Model NATO took place as part of the Model NATO course offered by the English section of the School’s Department of Languages and Cultures.
Vignesh Kannan, a young researcher at the Solid Mechanics Laboratory (LMS*), is leading a research team investigating a fundamental question: how can we explain the behavior of materials when subjected to extreme dynamic conditions?
École Polytechnique hosted the third edition of the international scientific conference “Réflexions,” organized by the Institut Polytechnique de Paris, of which École Polytechnique is a founding member. The Energy4Climate interdisciplinary research center and renowned researchers associated with École Polytechnique—Philippe Drobinski, Céline Guivarch, and Mathieu Xémard—led the roundtable discussions at this third edition.
École Polytechnique has confirmed its top position in the annual ranking of French engineering schools published by the specialist magazine L’Usine Nouvelle. L’X confirmed its top position in two of the four indicator categories in this ranking: internationalization and the integration of its students into professional life. It also secured first place in research, a category in which it ranked third in 2025.
From middle school to higher education, a variety of support measures can be implemented to encourage and assist women in achieving success in science. On Monday, 26 January, Juliette Toumelin (Head of the Equal Opportunities Division within the Corporate Social Responsibility and Environmental Responsibility Department) and Antigoni Alexandrou (CNRS Research Director at LOB) discussed the mentoring programmes available at École Polytechnique and the Institut Polytechnique de Paris.
