Brigitte Vallée (née Salesse) (born 6 June 1950, in Courbevoie, Hauts-de-Seine, France) is a French mathematician and computer scientist.
She entered the École Normale Supérieure de Jeunes Filles in 1970, and received her PhD in 1986 at the University of Caen (Lattice reduction algorithms in small dimensions).
[3] Vallée has been Director of Research at the French CNRS at Université de Caen,[4] since 2001 and specialized in computational number theory and analysis of algorithms.
In the early 90s, Brigitte Vallée's work on small modular squares allowed her to hold the fastest factorisation algorithm with a proved probabilistic complexity bound.
She was appointed a knight of the Legion of Honor by the Ministry of Higher Education and Research on 12 July 2013.
