Current Situation:

I study combinatorics, and more precisely graph theory. I am notably interested in planar graphs, algorithms, graph decompositions, in particular graph recoloring and other reconfiguration problems.

Luke Postle and I are the PIs of a Joint Bordeaux-Waterloo Research Grant (Colouring and Probabilities) for 2016-2017, renewed for 2017-2018. I am a member of the ANR Projects Distancia (Metric Graph Theory, 2017 - 2020) and HoSiGra (Homomorphism on Signed Graphs, 2017 - 2020).

I am currently supervising two PhD students: Paul Ouvrard (Combinatorial reconfiguration, co-supervised with Paul Dorbec and Cyril Gavoille) and Théo Pierron (Induction schemes: from languages separation to graph colorings, co-supervised with Éric Sopena and Marc Zeitoun), and one master student: Alexandre Blanché (Gallai's path decomposition conjecture, co-supervised with Nicolas Bonichon).

Paul Ouvrard and I are in charge of the Graphs & Optimization seminar at LaBRI. I am part of the scientific board of the GT COA.

I am an Associate Editor of Discrete Mathematics since April 2018.

Publications:

You can also find my master thesis (whose journal version is "2-distance coloring of sparse graphs") and my PhD thesis.

Vitae:

Born in Normandie (Northern France) on the 2nd of October 1990.
Master degree from
École Normale Supérieure de Lyon in 2011.
PhD from Université Montpellier, prepared in the ALgorithms, Graphs and COmbinatorics group of the LIRMM, with Benjamin Lévêque and Alexandre Pinlou, defended on the 9th of February 2015 (more details here).
Three-month postdoc at University of Waterloo (september-november 2015) with Luke Postle.
Chargée de recherche CNRS (permanent research-only position) at LaBRI, Bordeaux (since 1st of December 2015).

Fluent in French (mother tongue) and English. Notions of German and Spanish.

Previous responsibilities:

In 2010, during the first year of my masters, I had the opportunity to do an eight-week internship in the ACiD group of the School of Engineering and Computing Sciences, in Durham, United Kingdom. There, I worked with Daniël Paulusma and Matthew Johnson on the problem of graph recoloring. I still work on graph reconfiguration problems now and then, and organized a mini-symposium on that topic in SIAM DM'16 (Atlanta).

Feri Kardoš and I organized the 2017 edition of the JGA.

I was the PI of a PEPS grant DeKer (Dicharging and Kernelization) for 2017. I was a member of the ANR Project EGOS (Embedded Graphs and their Oriented Structures, 2012 - 2015) and of a PHC Proteus Project (Coloring graphs on surfaces, 2014-2015).

I supervised one master student: Paul Ouvrard (Reconfiguration of dominating sets under token sliding, co-supervised with Paul Dorbec, 2017).

Popular science:

Hervé Hocquard and I have been organizing the "Des enseignants dans les labos" operation (high school teachers get acquainted with the lab setting) in LaBRI since 2016. Guillaume Aupy and I organized a 2-day visit of LaBRI and INRIA Bordeaux Sud Ouest by 3rd-year Bachelor students from ÉNS de Lyon. I gave a talk in the "Printemps de la mixité" workshop in LaBRI.
