Cédric Patrice Thierry Villani (French: [sedʁik patʁis tjeʁi vilani]; born 5 October 1973) is a French mathematician and politician working primarily on partial differential equations, Riemannian geometry and mathematical physics. He was awarded the Fields Medal in 2010, and he was the director of Sorbonne University's Institut Henri Poincaré from 2009 to 2017. As of September 2025, he is a professor at the École normale supérieure de Rennes.

Villani has given two lectures at the Royal Institution, the first titled 'Birth of a Theorem'. The English translation of his book Théorème vivant (Living Theorem) has the same title.

In the book he describes the links between his research on kinetic theory and that of the mathematician Carlo Cercignani. Villani, in fact, proved the so-called Cercignani's conjecture. His second lecture at the Royal Institution is titled 'The Extraordinary Theorems of John Nash'.

Villani was elected as the deputy for Essonne's 5th constituency in the National Assembly, the lower house of the French Parliament, during the 2017 legislative election. He was elected as a member of La République En Marche! (LREM), but in May 2020 left the party to form a new party, Ecology, Democracy, Solidarity (EDS). Following the dissolution of EDS, Villani joined Ecology Generation, and ran for re-election in 2022 under the banner of the NUPES, ultimately losing his seat to LREM candidate Paul Midy by 19 votes.

He was elected vice president of the French Parliamentary Office for the Evaluation of Scientific and Technological Choices in July 2017.

Biography

After attending the Lycée Louis-le-Grand, Villani was admitted at the École Normale Supérieure in Paris and studied there from 1992 to 1996, after which he was appointed an agrégé préparateur at the same school. He received his doctorate at Paris Dauphine University in 1998, under the supervision of Pierre-Louis Lions, and became professor at the École normale supérieure de Lyon in 2000. He is now professor at the University of Lyon. He was director of the Institut Henri Poincaré in Paris from 2009 to 2017.

Mathematical work

Villani has worked on the theory of partial differential equations involved in statistical mechanics, specifically the Boltzmann equation, where, with Laurent Desvillettes, he was the first to prove how quickly convergence occurs for initial values not near equilibrium. He has written with Giuseppe Toscani on this subject. With Clément Mouhot, he has worked on nonlinear Landau damping.

Political career

In 2017, it was announced that Villani had been selected as a candidate for En Marche! (LREM) in the 2017 French legislative election, for Essonne's 5th constituency. In the first round of voting, Villani obtained 47% of the vote and was thus strongly placed for the second round which he won with 69.36% of the vote.

In 2019, Villani applied to be selected to lead the LREM candidate slate for the 2020 Paris election.

Other activities

France China Foundation, former Member of the Strategic Committee

In 2018, the French economics magazine Challenges said that Villani has been approached by Europanova thinktank. He presided over the jury of Digital In-Pulse, a startup program dedicated to accompanying entrepreneurs and start-ups, managed by Chinese corporate Huawei. The magazine also says that Villani is still the President of the endowment funds of the French Henri Poincaré Institute, and Huawei is among the top private donors.
