Régulation des conflits sociaux
Je m’intéresse à l’évolution de la coopération et plus précisément à la manière dont les groupes sociaux régulent les inévitables conflits d’intérêts qui existent en leurs seins. Ceux-ci comprennent la compétition entre reines, la production de mâles par les ouvrières, et la production de reines par les ouvrières dans les espèces primitivement eusociales où les ouvrières peuvent s’accoupler ou dans les espèces où la parthénogenèse thélytoque existe. J’étudie ces conflits expérimentalement dans la cadre de la sélection de parentèle, c’est-à-dire en prenant en compte les coûts et les bénéfices de la reproduction directe et de la reproduction indirecte de toutes les parties impliquées (reine, ouvrières pondeuses et non pondeuses). Ce travail est fait en collaboration avec Claudie Doums.
Regulation of social conflitcs
I am interested in the evolution of cooperation and, more specifically, in how social groups regulate the inevitable conflicts of interest between group members. These include competition between queens, male production by workers, and queen production by workers in primitively eusocial species where they can mate or in species where thelytokous parthenogenesis occurs. I experimentally study these reproductive conflicts using kin selection theory thinking, i.e. taking into account the inclusive fitness costs and expected benefits for all parties of interest involved (queen, reproducing workers, non-reproducing workers). Most of these works are done in collaboration with Claudie Doums.

Compromis compétition/colonisation
Je m’intéresse aussi aux stratégies au niveau de la colonie, comme le déménagement des colonies et la fondation de nouvelles colonies. J’étudie quels facteurs favorisent la fondation par fission (c.-à-d. la production de quelques propagules compétitives, formées par une reine accompagnée de nombreuses ouvrières) ou au contraire la fondation indépendante (c.-à-d. production de nombreuses propagules très dispersives, formées d’une reine volante seule). Ceci est fait à l’aide de simulations en collaboration avec Adam Cronin et Nicolas Loeuille.
Competition/colonization trade-off
I am also interested in colony-level strategies, such as colony relocation and the foundation of new colonies. Using agent-based modelling, I am starting to study which factors favour foundation by colony fission (i.e. production of few competitive propagules, formed by a queen accompanied by numerous workers) and which favour independent colony foundation (i.e. production of numerous high dispersal propagules, formed by a lone winged queen). This is done in collaboration with Adam Cronin and Nicolas Loeuille.

Évolution des castes et tampon social
En collaboration avec Mathieu Molet j’étudie aussi comment la socialité peut favoriser l’évolution de nouvelles morphologies de reines et d’ouvrières. La répartition des tâches et la division du travail qui caractérisent les sociétés d’insectes pourraient permettre de bénéficier de la présence d’individus meilleurs à réaliser certaines tâches même s’ils sont très mauvais aux autres.
Caste evolution and colony buffering
In collaboration with Mathieu Molet I also study whether and how colonies may facilitate the evolution of new queen and worker morphology. Indeed, division of labour and task partitioning that is characteristic of social insect societies may allow taking advantage of individuals better at one task even if they are disproportionately poor at other tasks.
