Cédric Patrice Thierry Villani (French: [se.dʁik pa.tʁis tjɛ.ʁi vi.la.ni]; born 5 October 1973) is a French mathematician working primarily on partial differential equations, Riemannian geometry and mathematical physics. He was awarded the Fields Medal in 2010 and is the director of Pierre and Marie Curie University's Institut Henri Poincaré.
Villani is also a politician. He sits in the National Assembly, the lower house of the French Parliament, representing Essonne's 5th constituency for En Marche!, the centrist political party of the French president Emmanuel Macron which currently holds the majority following the 2017 French legislative election.^{[2]} He was elected president of the French Parliamentary Office for the Evaluation of Scientific and Technological Choices in July 2017.

Biography
After attending the Lycée LouisleGrand, Villani was admitted at the École Normale Supérieure in Paris and studied there from 1992 to 1996. He was later appointed an assistant professor in the same school. He received his doctorate at Paris Dauphine University in 1998, under the supervision of PierreLouis Lions, and became professor at the École normale supérieure de Lyon in 2000. He is now professor at the University of Lyon. He has been the director of Institut Henri Poincaré in Paris since 2009.^{[3]}^{[4]}
He has held various visiting positions at Georgia Tech (Fall 1999), the University of California, Berkeley (Spring 2004), and the Institute for Advanced Study, Princeton (Spring 2009).^{[5]}
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.^{[4]} He has written with Giuseppe Toscani on this subject. With Clément Mouhot, he has worked on nonlinear Landau damping.^{[6]} He has worked on the theory of optimal transport and its applications to differential geometry, and with John Lott has defined a notion of bounded Ricci curvature for general measured length spaces.^{[7]}
Villani received the Fields Medal for his work on Landau damping and the Boltzmann equation.^{[4]} He described the development of his theorem in his autobiographical book Théorème vivant (2012), published in English translation as Birth of a Theorem: A Mathematical Adventure (2015). He gave a TED talk at the 2016 conference in Vancouver.^{[8]}
Political career
In 2017, it was announced that Villani has been selected as a candidate for En Marche! in the French legislative election, 2017, for Essonne's 5th constituency.^{[9]}^{[10]} In the first round of voting, Villani obtained 47% of the vote and was thus strongly placed for the second round^{[11]} which he won with 69.36% of the vote.^{[12]}
