Albert Fathi

Albert Fathi (born 27 October 1951, in Egypt) is an Egyptian-French mathematician. He specializes in dynamical systems and is currently a professor at the Georgia Institute of Technology.

Fathi attended the Collège des frères Lasalle in Cairo and grew up bilingual in French and Arabic. At age ten, he came as a political refugee to Paris and studied at the École normale supérieure in Saint-Cloud. He received in 1980 his PhD from the University of Paris 11 under Laurence Siebenmann with thesis Transformations et homéomorphismes préservant la mesure.^[1][2] From 1987 to 1992 he was a professor at the University of Florida. Since 1992 he has taught at the École normale supérieure de Lyon (unit of pure and applied mathematics). He has also taught at the École polytechnique.

He has been a visiting professor at the Institute for Advanced Study (1986/87),^[3] at the Universidad Complutense de Madrid (Instituto de Matemática Interdisciplinar), in Nanjing, in Cambridge and at MSRI. In 2013 he received the Sophie Germain Prize.^[4] He is a member of the Institut Universitaire de France.

At the International Congress of Mathematicians in 2014 in Seoul, Fathi was an Invited Speaker with talk Weak KAM Theory: the connection between Aubry-Mather theory and viscosity solutions of the Hamilton-Jacobi equation.
