Alumnus of the École normale supérieure de Saint-Cloud, Ghys obtained his Ph.D. in 1979 from the University of Lille with thesis "Sur les actions localement libres du groupe affine" written under the direction of Gilbert Hector.[1]

He is currently a CNRS "directeur de recherche" at the École normale supérieure in Lyon. He is also editor-in-chief of the Publications Mathématiques de l'IHÉS and a member of the French Academy of Sciences.

Ghys was an invited speaker at the International Congress of Mathematicians (ICM) in Kyoto in 1990, and a plenary speaker at the ICM in Madrid in 2006.[2] In 2015, he was awarded the inaugural Clay Award for Dissemination of Mathematical Knowledge.[3]

He co-authored the computer graphics mathematical movie Dimensions: A walk through mathematics!. His doctoral students include Serge Cantat.[1]
