Biographical details

I am interested in social evolution and kin-selected conflicts. I joined the University of Sydney in 2015 as a postdoctoral fellow in the Behaviour and Genetics of Social Insects Laboratory, investigating reproductive strategies in honey bees. I completed my PhD at the University Paris 13 in 2014, studying recognition systems and the regulation of reproduction in ants.

Research interests

My research focuses on the mechanisms underlying evolutionary conflicts in social insects, from the genomic level to the level of the society. I use behavioural and chemical ecology, genetics, genomics and bioinformatics, both in the field and in the lab.

Current projects

Honey bees are extremely polyandrous: the queen mates with numerous males, each fathering a different worker subfamily. This increases the genetic diversity within the colony, but also paves the way for genomic conflicts. Genes favouring worker reproduction are indeed predicted to be over-expressed when paternally inherited, while under-expressed when derived from the queen. Epigenetic modifications of the genome such as DNA methylation have the potential to regulate gene expression in a parent-of-origin manner. Furthermore, worker subfamilies differ markedly in their reproductive traits and show context-dependent reproductive strategies.

I am currently investigating the genome methylation profiles across castes and generations, and their link with worker reproduction.
