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.[2]

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 Benabou.[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.

gollark: Ah. I see.
gollark: <@&198138780132179968> <@270035320894914560>/aus210 has stolen my (enchanted with Unbreaking something/Mending) elytra.I was in T79/i02p/n64c/pjals' base (aus210 wanted help with some code, and they live in the same place with some weird connecting tunnels) and came across an armor stand (it was in an area of the base I was trusted in - pjals sometimes wants to demo stuff to me or get me to help debug, and the claim organization is really odd). I accidentally gave it my neural connector, and while trying to figure out how to get it back swapped my armor onto it (turns out shiftrightclick does that). Eventually I got them both back, but while my elytra was on the stand aus210 stole it. I asked for it back and they repeatedly denied it.They have claimed:- they can keep it because I intentionally left it there (this is wrong, and I said so)- there was no evidence that it was mine so they can keep it (...)EDIT: valithor got involved and got them to actually give it back, which they did after ~10 minutes of generally delaying, apparently leaving it in storage, and dropping it wrong.
gollark: Someone had a problem with two mutually recursive functions (one was defined after the other), so I fixed that for them. Then I explained stack overflows and how that made their design (`mainScreen` calls `itemScreen` calls `mainScreen`...) problematic. Their suggested solution was to just capture the error and restart the program. Since they weren't entirely sure how to do *that*, their idea was to make it constantly ping their webserver and have another computer reboot it if it stopped.
