The Faculty comprises 38 research laboratories, most of them in association with CNRS, Inserm, Inra, Inria and the Curie Institute.

In recent years the excellence of its research in mathematics has been rewarded by two Fields Medals awarded to Wendelin Werner in 2006 and Ngô Bào Châu in 2010; and research in physics has been recognised by the Nobel Prize, awarded to Albert Fert in 2007.

The Faculty of Science is located at the heart of the Orsay campus, an exceptional site extending over 2 km2 which includes a listed botanical garden.
