Olivier Jaillon has extensive experience in the comparative analysis of eukaryotic genome dynamics and evolution. Olivier analyzes how the characteristics of genome dynamics allow us to better understand evolution. He has spent years studying the traces in genomes of ancient events of macro-evolution such as whole genome duplications from which some major eukaryotic phyla derive (vertebrates, flowering plants, ciliates).
Today, he is interested in planktonic organisms. They have an essential role in the regulation of the climate and in the main terrestrial biogeochemical cycles. For these organisms, which are transported by ocean currents through biomes, the environmental constraints on their genome are linked to complex interactions between biology, physics and chemistry that occur in the « seascape ».
