Isabelle Gallagher


Isabelle Gallagher is a professor at the Université Paris-Diderot, and on secondment to the Departement de Mathematiques et Applications de l'École Normale Supérieure in Paris. She graduated from the Ecole Polytechnique in 1998 with a PhD from Sorbonne University (formerly UPMC) and was previously a CNRS researcher at the Université Paris Sud and at the Ecole Polytechnique.

sabelle Gallagher is a specialist in nonlinear partial differential equations, and in particular in fluid mechanics. She and her collaborators have made great progress on the 6th Hilbert problem, by trying to reconcile the microscopic and macroscopic views of fluid description.
Her work has been recognized by numerous awards, such as the Paul Doistau-Émile Blutet Prize 2008 and the Sophie Germain Prize 2018 of the Academy of Sciences, or the CNRS Silver Medal in 2016.
