Paris-Saclay University. Paris-Saclay University (, ) is a combined technological research institute and public research university in Orsay, 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, among them modern algebraic geometry and catastrophe theory. 

Paris-Saclay has two main campuses: the 495-acre Plateau urban campus, straddling Orsay, Gif-sur-Yvette and Palaiseau (with the Campus Agro Paris-Saclay) and centered on the Quartier de Moulon; and the historic campus in the valley, centered around the Château de Launay, the university's former headquarters. It also has several decentralized campuses, such as the medical campus in Bicêtre Hospital at Kremlin-Bicêtre, and the law faculty campus at Sceaux. The University of Versailles and the University of Évry, both part of Paris-Saclay, have campuses in Versailles, Guyancourt, Vélizy-Villacoublay, Saint-Germain-en-Laye and Évry-Courcouronnes.

As of 2021, 11 Fields Medalists and 4 Nobel Prize winners have been affiliated with the university and its associated research institutes.

History 
In 2019, the Paris-Saclay University succeeded University of Paris-Sud founded in 1971, which itself succeeded to University of Paris (in Orsay), founded . 

The Paris-Saclay University was established in 2015 as a universities community (ComUE) and in 2019 as a collegiate university, with the aim to become a top-ranking, research-focused French university.

20th century

University of Paris research centres in Orsay, on the Saclay plateau 

After World War II, the rapid growth of nuclear physics and chemistry meant that research needed more and more powerful accelerators, which required large areas. The University of Paris, the École Normale Supérieure and the Collège de France looked for space in the south of Paris near Orsay. 

As early as the 1940s, the French physicists Irène Joliot-Curie and Frédéric Joliot-Curie, professors at the Faculty of Science at the University of Paris, had already envisaged decentralising the university to the southern suburbs of Paris, near Versailles. In 1942, Irène Joliot-Curie even informed the university's rector of the existence of a potential site near Orsay, on the Saclay plateau. 

In the 1950s, a number of Grandes Ecoles and university research departments were set up in the immediate vicinity of the Saclay plateau. In 1954, France decided to combine its participation in CERN with the development of its own nuclear physics research.  

In 1955, the University of Paris moved into the Saclay plateau with the purchase of 50 hectares of land in Orsay. Irène Joliot-Curie proposed the creation of the Orsay Institute of Nuclear Physics, and construction work began in 1955. She died in 1956, and Frédéric became the Institute's first director. At the same time, the Orsay Linear Accelerator Laboratory (LAL) of the University of Paris was built. 

The rapid increase of students and the teaching situation at the Sorbonne (the main campus of the University of Paris) was becoming increasingly critical. So in 1958 it was decided to transfer some of the science teaching at the University of Paris to Orsay.

The University of Paris-Sud 

In 1965, the Orsay science campus officially became independent from the University of Paris. After being the Orsay Faculty of Sciences of the University of Paris, separate from the Paris Faculty of Sciences, it became a full university, the University of Paris-Sud (Paris XI) in 1971. The Faculty of Sciences was joined by the Faculty of Medicine at Kremlin-Bicêtre, the Jean Monnet Faculty of Law and Economics at Sceaux and the Faculty of Pharmacy at Châtenay-Malabry, creating a multidisciplinary university in the south of Paris.

21st century

The Campus Paris-Saclay scientific cooperation foundation (FCS) 
In 2007, a research and higher education hub was created in Orsay and Saclay. The hub has three founding members: the University of Paris-Sud, the University of Versailles and the École normale supérieure de Cachan, the future ‘ENS Paris-Saclay’.

In 2008, the University of Paris-Sud and the University of Versailles were among the 21 winning institutions of the France's Plan Campus, with which the Saclay research and higher education hub is associated. These institutions then embarked on a larger-scale cooperation, namely the creation of a collegiate university: the Université Paris-Saclay. The university project was launched following its validation by the French Ministry of Higher Education and Research as part of the Campus Plan.

The Campus Paris-Saclay scientific cooperation foundation, chaired at the time by Alain Bravo, was set up to bring together the various academic and scientific establishments, manage the Digiteo and Triangle de la physique advanced research thematic networks (RTRA) and create the community. With the planned development of the Paris-Saclay technology hub, many institutions are planning to move there.

The university system 'Université Paris-Saclay' 
In 2014, the various members adopted the statutes of the Paris-Saclay University system (ComUE), enabling it to award bachelor's, master's and doctoral degrees. Ultimately, the university system is to become a full university. 

The university system's first academic year started in September 2015.

To be recognized as an entity of sufficient size and quality, the university regroups some of the top grandes écoles in France with public universities under a single campus on the Saclay plateau. Each member institution will remain independent but share a significant portion of existing and newly invested resources. This follows a model similar to the one adopted by University of Oxford and Cambridge, where each constituent college keeps its independence while being grouped under a 'university'. According to Dominique Vernay, chairman of the foundation developing Paris-Saclay, the university aims at a top-ten position in the Academic Ranking of World Universities (ARWU), but "the first goal is to be the top university in continental Europe".

Confronted with disagreements between its members (between the schools and universities, or between their supervisory ministries), the project stagnated, as the Cour des Comptes noted in its report of 8 February 2017, pointing in particular to a lack of housing and transport facilities, as well as a lack of strategic vision, despite the five billion euros planned (committed or envisaged). In 2017, the University of Paris-Sud proposed merging with the university system (ComUE) to create the Paris-Saclay University as a collegiate university, and integrating the schools into the future institution as component institutions. This stalemate led President Emmanuel Macron to announce on 25 October 2017, during his inauguration of CentraleSupélec's new buildings at Paris-Saclay, the separation of the various members into two university entities: the Paris-Saclay University and the Polytechnic Institute of Paris.

On 25 October 2017, French President Emmanuel Macron inaugurated the new Orsay Graduate School of Mathematics, which brings together the mathematics laboratory teams of the Paris-Saclay University and the CNRS, some of the teaching staff, and the Jacques Hadamard University Library.

The collegiate university 

In January 2020, it replaced University of Paris-Sud and in 2025, University of Versailles and University of Evry will merge with it as well. They should evolve towards the status of an ‘integrated university’, and be renamed Paris-Saclay University in Versailles and Paris-Saclay University in Évry.

Every year since 2020, Paris-Saclay has achieved its best performance in the Shanghai rankings, ranking 1st in the world in mathematics and 9th in physics.

In April 2022, the Paris-Saclay University inaugurated the new 'Agro Paris-Saclay Campus', which covers 4.2 hectares in the commune of Palaiseau, near Orsay. It will be hosting nearly 2,000 students and 1,350 teacher-researchers, researchers, technicians and staff from the AgroParisTech Grande École of the Paris-Saclay University.

On 18 April 2023, Paris-Saclay University opened France's largest academic research hub for pharmaceuticals, the Henri-Moissan Centre, bringing together its School of Pharmacy, its chemistry and biology departments and the Orsay Institute of Molecular Chemistry and Materials in a single centre. More than 3,000 students and 1,000 researchers-teachers and administrative staff have gradually moved in since the start of the new academic year in September 2022.

Since October 2023, the university has been a partner of the French private Grande École IPSA for double degrees in aerospace. 

In February 2024, Paris-Saclay, which brings together nearly 50,000 students, is facing a leadership crisis. The Board of Administrators has still not been able to elect its future chairman and has been under the supervision of a provisional administrator for several months. After several months of crisis, the former provisional administrator Camille Galap was elected to head the flagship French university on 11 June 2024, with the promise of getting the institution out of the institutional difficulties it is going through. Indeed, the greater presence of qualified external figures on the board of directors, than representatives of teachers, researchers or students, has caused an institutional blockage. A situation made possible because of the university's exceptional statuses.

Organisation 
The Paris-Saclay University consists of five faculties in Sciences, Medicine, Pharmacy, Law-Economics-Management, and Sports Sciences; an Engineering school; three technical institutes specialised in scientific and technical subjects in Cachan, Orsay, and Sceaux; and an undergraduate university school.

The university also brings together four : CentraleSupélec, AgroParisTech, ENS Paris-Saclay and the Institut d'Optique Graduate School, with two associate institutions: Versailles Saint-Quentin-en-Yvelines University (UVSQ) and University of Évry Val d'Essonne (UEVE).

It combines resources from the following French universities and grandes écoles, as well as partial resources from various research organizations and the Systematic Paris-Region cluster:

Initially, the community of universities also included five other grandes écoles: École Polytechnique, Télécom Paris, Telecom SudParis, ENSTA Paris and ENSAE Paris. However, due to differences in University set-up, these five grandes écoles created their own separate university Polytechnic Institute of Paris. This was announced by French President Emmanuel Macron during a speech in Paris-Saclay. Both of these clusters plan to co-operate and they engage in organization of several master's degrees with the Paris-Saclay University.

Orsay

The Plateau 

The main Paris-Saclay campus, covering 495 acres (200 ha), is centered on the Saclay Plateau and its Quartier de Moulon ("the Urban Campus") in Orsay, around 20 km south of downtown Paris, and extends into the surrounding areas of Gif-sur-Yvette and Palaiseau. The Plateau is home to the new buildings of the Faculty of Pharmacy, the departments of chemistry, biology and physics of the Faculty of Sciences, The Lumen, the university's main library, the École normale supérieure, the CentraleSupélec engineering grande école. 

The adjacent areas of the Plateau, in the neighboring commune of Palaiseau, include the main buildings of AgroParisTech, the university's Institute of Life Sciences and Industries and the Environment, and the university's Center for Nanosciences and Nanotechnologies (C2N).

The Valley 
Also, the campus historically extends to the south of the Bois de la Guyonnerie, in the Valley. Close to the city center of Orsay and the RER station Orsay-Ville, the Valley campus is centered around the Château de Launay. It houses the other departments of the Faculty of Sciences, the university science libraries such as Hadamard Library, and the main laboratories.
