Christophe Breuil (French: [bʁøj]; born 1968) is a French mathematician, who works in algebraic geometry and number theory.

Academic life[edit]

Breuil attended schools in Brive-la-Gaillarde and Toulouse and studied from 1990 to 1992 at the École Polytechnique.[citation needed]

In 1993, he obtained his DEA degree at the Paris-Sud 11 University located in Orsay.[citation needed]

From 1993 to 1996 he conducted research at the École Polytechnique and taught simultaneously at the University of Paris-Sud, Orsay.[citation needed]

In 1996, he received his PhD from the École Polytechnique, supervised by Jean-Marc Fontaine with the thesis "Cohomologie log-cristalline et représentations galoisiennes p -adiques".[citation needed]

In 1997, he gave the Cours Peccot at the Collège de France.[citation needed]

In 2001 he obtained a habilitation degree entitled "Aspects entiers de la théorie de Hodge p-adique et applications" at Paris-Sud 11 University.[citation needed]

Between 2002 to 2010 he was at the IHES.[citation needed]

From 2010 he has been in the Mathematics Department of University of Paris-Sud as Director of Research with the CNRS.

In 2007/08 he was a visiting professor at Columbia University.[citation needed]

He was an invited speaker in International Congress of Mathematicians 2010, Hyderabad on the topic of "Number Theory."[1]


In 1993 he was awarded the Prix Gaston Julia at the École Polytechnique.

In 2002 he received the Grand Prix Jacques Herbrand (fr) of the French Academy of Sciences and the 2006 Prix Dargelos Anciens Élèves of the École Polytechnique.


With Fred Diamond, Richard Taylor and Brian Conrad in 1999, he proved the Taniyama–Shimura conjecture, which previously had only been proved in a special case by Andrew Wiles and Taylor. Then he worked on the p-adic Langlands conjecture.
