# Laure Saint-Raymond

Laure Saint-Raymond (born 1975) is a French mathematician, and a professor of mathematics at Institut des Hautes Études Scientifiques (IHES). She was previously a professor at École Normale Supérieure de Lyon. She is known for her work in partial differential equations, and in particular for her contributions to the mathematically rigorous study of the connections between interacting particle systems, the Boltzmann equation, and fluid mechanics. In 2008 she was awarded the European Mathematical Society Prize, with her citation reading:
   Saint-Raymond is well known for her outstanding results on nonlinear partial differential equations in the dynamics of gases and plasmas and also in fluid dynamics. [...] Saint-Raymond is at the origin of several outstanding and difficult results in the field of nonlinear partial differential equations of mathematical physics. She is one of the most brilliant young mathematicians in her generation.

## Biography

Laure Saint-Raymond studied in Paris, entering École Normale Supérieure in 1994. In 1996, she received a Master's degrees in plasma physics from Versailles Saint-Quentin-en-Yvelines University and in applied mathematics from Pierre and Marie Curie University. In 2000 she finished her Ph.D. in applied mathematics at Paris Diderot University, under the supervision of François Golse.
She worked for two years for the French National Centre for Scientific Research, and was named in 2002 full professor of mathematics at the Pierre and Marie Curie University at the age of 27. In 2007, she moved to the École Normale Supérieure, and is now professor at the École Normale Supérieure de Lyon. In 2021, she joined the Institut des Hautes Études Scientifiques in Bures-sur-Yvette, France as permanent professor, the first woman to hold that position in the history of the Institute.
She is the mother of six children.

## Awards and honors

## Research

In 2009, her work was summarized by the Satter Prize committee as:
   Her research has focused on the study of problems in mathematical physics, including the Boltzmann equation and its fluid dynamic limits, the Vlasov-Poisson system and its gyrokinetic limit, and problems of rotating fluids coming from geophysics. Her most striking work concerns the study of the hydrodynamic limits of the Boltzmann equation in the kinetic theory of gases, where she answered part of a question posed by Hilbert within the framework of his sixth problem.
