Chéritat earned a licenciate in mathematics in 1995 from the École Normale Supérieure, a diplôme d'études approfondies in pure mathematics in 1996 from the University of Paris-Sud, and a master's degree in pure and applied mathematics and informatics in 1998 from the École Normale Supérieure.[1] He defended his doctoral thesis in 2001 from the University of Paris-Sud, under the supervision of Adrien Douady,[3] and completed his habilitation in 2008 from the University of Toulouse.[1] He worked as a maître de conférences at the University of Toulouse from 2002 until 2007, when he moved to the Institut de Mathématiques de Toulouse.[1]

In 2006, Chéritat won the Leconte Prize of the French Academy of Sciences.[4] He was an invited speaker at the International Congress of Mathematicians in 2010.[5] In 2012, he became one of the inaugural fellows of the American Mathematical Society.[6]
