Marie-Françoise Roy

Marie-Françoise Roy (born 28 April 1950 in Paris) is a French mathematician noted for her work in real algebraic geometry. She has been Professor of Mathematics at the University of Rennes 1 since 1985 and in 2009 was made a Chevalier of the French Legion of Honour. In 2004, she received an Irène Joliot-Curie Prize.

Research
Roy works in real algebraic geometry in particular real spectra and, most recently, in complexity of algorithms in real algebraic geometry and also the applications.

Education and career
Marie-Françoise Roy got her education at École Normale Supérieure de jeunes filles and was an assistant professor at Université Paris Nord during 1973. She received her PhD at Université Paris Nord in 1980, supervised by Jean Bénabou.

From 1981 she spent two years at Abdou Moumouni University in Niger. In 1985 she became a professor at University of Rennes 1 in Rennes, France.

Service
Roy was president of Société Mathématique de France from 2004 to 2007.

In 1986, Roy was one of the founders of European Women in Mathematics (EWM), and was the convenor (president) of EWM 2009–2013. In 1987 she co-founded the French organization for women in mathematics, Femmes et Mathématiques, and became the organization's first president.

Roy is scientific officer for Sub-Saharan Africa in Centre International de Mathématiques Pures et Appliquées, CIMPA]. Roy is president of Association d'Echanges Culturels Cesson Dankassari (Tarbiyya-Tatali) an organization working for joint activities in a commune Dan-Cassari in Niger and the French commune Cesson-Sévigné.
