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.^[3] She received her PhD at Université Paris Nord in 1980, supervised by Jean Bénabou.^[4]

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.^[5]

In 1986, Roy was one of the founders^[6] of European Women in Mathematics (EWM), and was the convenor (president) of EWM 2009–2013.^[7] 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.^[8] 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.
