Marie-Claude Arnaud-Delabrière (born 24 February 1963)[1] is a French mathematician, specializing in dynamical systems.
[3] Arnaud was a mathematics student at the École normale supérieure (Paris) from 1983 to 1987; she earned a bachelor's degree in 1984, an agrégation in 1985, and a diplôme d'études approfondies in 1986.
[1] In 2010, Arnaud was a speaker at the International Congress of Mathematicians.
[5] In 2011 she won the Gabrielle Sand and M. Guido Triossi Prize [fr] of the French Academy of Sciences for her work on Hamiltonian dynamical systems, and in particular on the regularity of invariant curves in the dynamics of billiards.
[2][6] She was named to the Institut Universitaire de France as a senior member in 2013.
