Biography

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 Girard's paradox, linear logic; the geometry of interaction; ludics; and the mustard watch.[1]

He obtained the CNRS Silver medal in 1983 and is a member of the French Academy of Sciences.
