Research interests

We study genetic variation within various insect species, for the purpose of inferring their evolutionary history and/or evaluating their capacity to disperse.

Among others: 

  1. We investigated the influence of past climate changes that occurred during the late Pleistocene on several insect species.

  2. We conducted several comparative phylogeographic studies (leaf beetles, bark beetles, bees), comparing variation at multiple loci across several species. Our goal is to investigate the combined influence of species-specific traits (e.g., host plant abundance, dispersal) and environmental disturbances on phylogeographic patterns, but also to explore inter-species hybridization through patterns of mitochondrial and nuclear introgression.

  3. We compared hypotheses over the recent colonization and migration history of several insect species.

We also evaluate and develop methods to analyse DNA sequence variation in an evolutionary context.

Recently, we started a study of population adaptation of specialized herbivorous insects, at the genomic level.
