Paris Diderot University, also known as Université Paris Diderot - Paris 7, is a French leading University located in Paris, France. It is one of the heirs of the Faculty of Sciences of the University of Paris (together with Paris 6), which was one of the earliest established in Europe, founded in the mid 12th century and formally dissolved in 1970. It adopted its current name in 1994. The University is famous for its teaching in Science, especially in Mathematics. Indeed, the Laboratoire de Probabilités et Modèles Aléatoires (Laboratory of Probability and Random Models), which is one of the centers of research of Paris Diderot University, has discovered many fundamental results of the theory of Probability. But the University is also a place for multidisciplinary education: currently, there are 2300 educators and researchers, 1100 administrative personnel and 26,000 students studying humanities, science, and medicine. That's why it always has been ranked as one of the three best French Universities.
