I am a Maître de conférences at University of Caen Normandy starting from September 2018.
Here are my (rarely updated) CVs in English and in French.
My husband, Arnaud Mortier, is also a mathematician.
Research interests
My interests revolve
around the
vast notions of structure and braiding, in particular their
homological, categorical, and topological
aspects. This includes the YangBaxter equation, braid
groups, knots and their generalized versions (virtual, welded, twisted,
handlebody, 2dimensional), knotted graphs, quantum invariants,
coloring (e.g., quandle) invariants,
quantum (quasi)shuffle algebras, braided systems, self and
mutidistributivity, Laver tables, cycle sets, Young tableaux,
categorification
of algebraic structures, Hopf
algebras and Hopf bimodules, YetterDrinfel'd modules, RotaBaxter algebras, operads, etc. This small video
introduces some of these notions for nonmathematicians. I like elegant and elucidating mathematics. Sharing it is a real pleasure. That is why I engage in outreach activities whenever possible. Currently I am a part of Labosaïque. In the past, I coorganized the Mathematics Club of the University of Nantes, and took part in the 5 minutes Lebesgue adventure.
