A CNRS research fellow at the Plasma Physics Laboratory (LPP*), Lina Hadid specializes in space plasmas and, in particular, the interaction of the solar wind within the solar system. Interview with a passionate researcher involved in numerous space exploration missions who has just received the Young Researcher Award from the Société Française d’Astronomie et d’Astrophysique.
Sergio Rajsbaum, researcher at the Universidad Nacional Autónoma de México (UNAM) and CNRS, has spent seven months at École Polytechnique as a Gaspard Monge Visiting Professor. During his visit, he and Professor Éric Goubault further developed a new research line focused on the connections between epistemic logic and distributed computing. This was also the theme of an international workshop organized by the researchers on June 15 – 17, 2026.
Three Master of Science & Technology students won this year's EuroTeQaThon with their project. The international student competition organised by the European university alliance EuroTeQ took place from 13 to 15 June 2026 at the Technical University of Denmark (DTU). This first-place finish at the EuroTeQaThon marks a first for l'X since the competition was created.
Elisabeth Maria Niel, Simone Kotthaus, Chloé Techens, and Clément Bonet have received funding from the École Polytechnique Foundation. These Launching Packages will enable them to set up their research teams within École Polytechnique’s laboratories.
The Structural Biology of the Cell Laboratory (BIOC*), in collaboration with Ifremer in Brest, the CBI in Toulouse, and Institut Pasteur, has identified a molecule in archaea capable of putting the ribosome, a cellular machinery essential to cells, into a state of dormancy. This “hibernation factor” binds to the ribosome when external conditions are unfavorable.
Speaking to the X25 cohort of École Polytechnique students, Antoine Bordes, Chief Scientific Officer at Helsing, emphasised the importance of developing technologies that serve European defence, whilst not overlooking the issue of the responsibility of engineers and military personnel. With their first-class training in science, and now in artificial intelligence, students at École Polytechnique will be able to innovate within the government or private companies to build a society capable of protecting its values by placing people at the heart of decision-making.
Philippe Hazet, head of the École Polytechnique X-UP incubator, outlines the key considerations behind our participation in the 2026 edition of the Viva Technology trade fair. This major global event for innovation and new technologies will take place from 17 to 20 June at the Porte de Versailles in Paris.
Nadir Soucha, a third-year doctoral student in management sciences at L' X Interdisciplinary Laboratory (LINX*) and the automotive supplier Valeo, is conducting a comparative study of emissions from industrial production in France and India.
Entrepreneurship, Innovation, Sustainable Development
When they founded the start-up Jane in 2023, Simon Heurtebise and Nathan Bouldoires wanted to be part of an increasingly significant initiative: collective self-consumption. With their software, they simplify the administrative management of these complex projects and thus contribute to the green transition by promoting the sharing of renewable energy, particularly solar power. In 2024–2025, they received support from École polytechnique’s incubator, X-UP, which enabled them to bring their idea to fruition. This support demonstrates the importance École polytechnique places on supporting projects that are meaningful and beneficial to society.
In May, Micah Goldblum, an assistant professor of electrical engineering at Columbia University, spent four weeks at l’X as an Alliance Visiting Professor. His stay at the Center for Applied Mathematics (CMAP) enabled him and El Mahdi El Mhamdi, a professor at École Polytechnique, to advance their international scientific collaboration, which also involves PhD students from both institutions.
X2009 and Professor Monge at the Laurent Schwartz Mathematics Center (CMLS*), Martin Leguil and his colleague Davi Obata received the Lounsbery 250 Years Award. This award was established to celebrate Franco-American ties in science.
École Polytechnique is expanding its artificial intelligence curriculum with a new mandatory AI course for all second-year students in the Cycle Ingénieur Polytechnicien program. Set to launch in September 2026, this new course aims to ensure that every future graduate of the Cycle Ingénieur Polytechnicien program possesses the essential skills to understand, apply, and critically evaluate a technology that is already redefining the boundaries of knowledge.
