I am a Hamilton Research Fellow at Hamilton Mathematics Institute and Trinity College Dublin (Ireland), in the research group of Vladimir Dotsenko. Here is my CV in English, and a less regularly updated CV in French.
My husband, Arnaud Mortier, is also a mathematician, working at Dublin City University (Ireland).
In 2017 (Hilary Term) I was teaching Module MA3416: Group Representations.
In 2017 (Michaelmas Term) I will be teaching Module MA1S11: Mathematics for Scientists.
With Vladimir Dotsenko we are organising a Hamilton Mathematics Institute workshop Geometry and combinatorics of associativity, to be held in Dublin on October 2327 2017. Registration is now open. All are welcome!
Research interests
My interests travel
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. For instance, last year I coorganized the Mathematics Club of the University of Nantes, and took part in the 5 minutes Lebesgue adventure.
