Albert Fathi

Albert Fathi is a mathematician holding dual roles: Professor Emeritus at École Normale Supérieure de Lyon (since 2016) and Professor of the Practice at Georgia Institute of Technology (since 2017). His career includes positions at the CNRS (1974–1992), University of Florida (1987–1992), and teaching at École Polytechnique. He specializes in dynamical systems, Lagrangian mechanics, and Hamilton-Jacobi equations, pioneering the Weak KAM Theory during his tenure as Director of Studies in Mathematics at ENS Lyon (1996).

Education:
- Former student of ENS Saint-Cloud.
- Defended doctoral thesis *Transformations et homéomorphismes préservant la mesure* (1980) under Laurence Carl Siebenmann and Michael Herman.

Research Focus:
Fathi’s work bridges Lagrangian dynamical systems and Hamilton-Jacobi equations. He is renowned for founding the Weak KAM Theory, a cornerstone in the study of dynamical systems and their invariant structures. His contributions emphasize analytical approaches to Hamiltonian systems and their applications in geometric mechanics.
