École polytechnique universitaire de Paris-Saclay

Paris-Saclay is a research-intensive and business cluster currently under construction in the south of Paris, France. It encompasses research facilities, two French major universities with higher education institutions (grandes écoles) and also research centers of private companies. In 2013, the Technology Review put Paris-Saclay in the top 8 world research clusters. In 2014, it comprised almost 15% of French scientific research capacity. The earliest settlements are from the 1950s, and this area was subsequently extended several times during the 1970s and 2000s. Several projects are underway to continue the development of the campus, including the relocation of some facilities. The area is now home to many of the Europe's largest high-tech corporations, and to the two French universities Paris-Saclay University (CentraleSupélec, ENS Paris-Saclay, Paris-Saclay Faculty of Science, etc.) and the Polytechnic Institute of Paris (École Polytechnique, Telecom Paris, etc.). The Paris-Saclay University was ranked 15th in the world in the 2023 ARWU ranking. It was also placed 1st in the world for Mathematics and 9th in the world for Physics (1st in Europe).The goal was to strengthen the cluster to build an international scientific and technological hub that can compete with other high-technology business districts, such as Silicon Valley or Cambridge, MA. This project started in 2006 and is likely to end in 2022. The main part is the construction of the campus du plateau de Saclay.

Paris-Saclay University (French: Université Paris-Saclay) is a combined technological research institute and public research university in Paris, France. Paris-Saclay was established in 2019 after the merger of four technical grandes écoles, as well as several technological institutes, engineering schools, and research facilities; giving it fifteen constituent colleges with over 48,000 students combined.With the merger, the French government has explicitly voiced their wish to rival top American technological research institutes, such as the MIT. The university has over 275 laboratories in particle physics, nuclear physics, astrophysics, atomic physics and molecular physics, condensed matter physics, theoretical physics, electronics, nanoscience and nanotechnology. It is part of the larger Paris-Saclay cluster, which is a research-intensive academic campus encompassing Paris-Saclay University, the Polytechnic Institute of Paris, combined with a business cluster for high-technology corporations. Paris-Saclay notably also includes the Institut des Hautes Études Scientifiques, where many contributions to the development of modern mathematics have been made, amongst them modern algebraic geometry and catastrophe theory.As of 2021, 11 Fields Medalists and 4 Nobel Prize winners have been affiliated with the university and its associated research institutes.
