Research theme:

 

My work aims to better understand the evolution of cooperation in the living world. Cooperation is a widespread phenomenon that occurs at all levels of biological organization, from genomes to ecosystems. I use a combination of different methods of molecular ecology and evolutionary genetics to study key factors that favor and transform cooperation phenomena occurring both in symbiotic associations (mutualism between insects and microorganisms) and in insect societies (cooperation and division of labour among colony members). I investigate these questions by developing the following lines of research:

 

  • Evolutionary dynamics of host-Wolbachia associations in insects (wasps, ants, moths)

 

  • Genetics and evolution of invasive populations in social insects (termites, hornets)

 

  • Evolution of reproductive and breeding systems in social insects (termites, hornets)

 

  • Evolution of nutritional gut microbial communities in termites

 

Key words: Cooperation, Symbiosis, Mutualism, Sociality, Reproductive Systems, Inbreeding, Population Genetics, Molecular Phylogenetics, Insects, Microorganisms
