Since October 2017, I am part of the AlGCO team at the LIRMM (Montpellier, France), with teaching duties at the Université Paul Valéry.

I am interested in planar maps and graphs. For the moment, I am working on different kinds of graph drawing, and in combinatorial optimization (mainly around the theme of "power domination").
I defended my thesis (with title: "Planar graphs: non-aligned drawings, power domination and enumeration of Eulerian orientations") on June 14th, 2017, at the University of Bordeaux. My supervisors were Nicolas Bonichon and Paul Dorbec.

Research

I am generally interested in problems concerning planar graphs, especially graph drawing, enumeration and power domination.
