Jean-Yves Girard is an alumnus of the École normale supérieure de Saint-Cloud.
He made a name for himself in the 1970s with his proof of strong normalization in a system of second-order logic called System F. This result gave a new proof of Takeuti's conjecture, which was proven a few years earlier by William W. Tait, Moto-o Takahashi and Dag Prawitz. For this purpose, he introduced the notion of reducibility candidate ("candidat de réducibilité"). He is also credited with the discovery of linear logic; the geometry of interaction; ludics; and the mustard watch.
