I am working on the genetic structure of forest insects at different spatial scales, with the aim of identifying the processes that limit gene flow and of characterising and analysing hybrid zones (between species, or introgression between populations). I use tools from population genetics and genomics, phylogenomics, as well as field surveys. My main biological model is the pine processionary caterpillar (Mediterranean complex Thaumetopoea pityocampa / T. wilkinsoni), which is expanding northwards and to higher altitudes in France due to global warming. My projects also focus on changes in life cycles and their consequences for evolutionary processes. In this context, I am particularly interested in a processionary moth population discovered in Portugal in the late 1990s, whose life cycle is out of sync (a case of allochronic differentiation). In parallel, I am studying a number of cases of biological invasions, particularly among bark beetles and longhorn beetles.

Keywords: invasion biology; spread; phenology; forest insects; genomics; ecology; processionary moths; bark beetles.
