Since October 2016, I am a CNRS researcher. I am currently working in Lyon in the LIRIS laborarory in the team GOAL (Graphs algOrithms and AppLications). Previously I was in Grenoble in the GSCOP laboratory where I was a member of the Combinatorial Optimization (OC) team.
We are currently organizing a virtual seminar until things go back to normal. There is one seminar every two weeks usually. For more information, you can go to the GRAA (Graphes en Rhone Alpes Auvergne) webpage. Most of the talks are recorded. If you want to see more talks, you can for instance enjoy the Frontiers of Parameterized Complexity registered presentations, as well as KAIST Discrete Mathematics seminars or Matroid union seminars. I order to see live seminars (about discrete mathematics and graph theory or algorithms), many of the announcements are centralized here or there.
Formerly, I was an ATER (temporary assistant professor position) in Ecole Centrale de Lyon during the academic year 20152016. I was a member of the LIRIS laboratory in the GOAL (Graphes, AlgOrithmes et AppLications) team. Before, I was a postodoctoral fellow at the Department of Mathematics and Statistics at McGill University where I worked with Adrian Vetta. My scholarship was partially funded by the GERAD (Groupe d'études et de recherche en analyse des décisions) at Université de Montréal.
I have defended my PhD the 9th of December 2013 under the direction of Stéphane Bessy and Stéphan Thomassé at the Université Montpellier 2 (LIRMM). Its title was "Hitting sets, VCdimension and Multicut". The manuscript can be found there and the slides of the defense can be found there.
I am interested in graph theory, game theory and combinatorics.
My topics of research include but are not limited to:
 Graph reconfigurations problems, especially reconfiguration of colorings and independent sets.
 Structural graph theory and all its applications including graph coloring.
 Parameterized algorithms and polynomial kernels.
 Economic game theory including spectrum auctions and payoff distributions.
I am the french PI of the ANR project GrR (Graph Reconfiguration).
I was the frech PI of the PHC francojapanese "Sakura" project DATCORE (Development of Algorithmic Techniques for COmbinatorial REconfiguration). In 2019, I coorganized (with Marthe Bonamy), the third edition of the CoRe (Combinatorial Reconfiguration) workshop in Aussois (see here for more information).
Here is a list of current and former PhD students:
 2020.... Quentin Deschamps, LIRIS, Université Lyon 1 (with Hamamache Kheddouci and Aline Parreau).
 20182021 Valentin Bartier, GSCOP, GrenobleINP (with Myriam Preissmann).
 20172020. Alice Joffard, LIRIS, Université Lyon 1 (with Hamamache Kheddouci).
 20162019. Marc Heinrich, LIRIS, Université Lyon 1 (with Eric Duchêne and Sylvain Gravier). Marc is now postdoc at Leeds University.
