My activity

I started a PhD in October 2020 on the ERC project ‘GAIA’ (A Genomic and Macroevolutionary Approach to Studying Diversification in an Insect Plant Arms Race). I study the evolution within the Papilionidae family through genomic and macroevolutionary approaches, especially in the context of the arms race between these swallowtail butterflies and their host plants. I am reconstructing the phylogeny of the ~600 species of Papilionidae (32 genera worldwide), using long fragment sequencing (Oxford Nanopore Technology) and Illumina approaches. The aim is then to study the synchronous nature of the evolution of these phytophagous insects and their associated plants, to highlight a reciprocity of their interactions as well as an increased diversification of these groups compared to sister groups without such interactions. Finally, we would like to further identify the genomic mechanisms involved in host plant associations and/or shifts using transcripomic approaches.
