I am a member of ROC research group within the LAAS lab.

I am interested in graph theory and discrete optimization in general.

My doctoral dissertation as well as my habilitation deal with identifying codes in graphs. My Ph.D. supervisor was Sylvain Gravier ; I used to be the co-supervisor of Marwane Bouznif's, Julien Darlay's and Widad Dali's doctoral works. I also supervised Pierre Coupechoux's Ph.D.

I belong to the maths à modeler transdisciplinary research group. I am also a member of the informal research group TORO (Toulouse Optimization and Operations Research).

Here are the publications in refeered international journals I contributed to:
