Olivier Jaillon is a Principal Investigator at CEA–Genoscope. He develops and applies comparative genomic approaches to understand eukaryotic genome evolution, from genome architecture constraints to macro-evolutionary transitions such as whole-genome duplications across major lineages.
He is currently conducting ‘Seascape Genomics’ investigations, which combines environmental genomics with oceanographic context to model the large-scale organisation and stability of planktonic communities, and to predict how they will reorganise in response to climate change. In this context, he is particularly involved in several scientific projects related to the Tara Oceans expeditions https://www.tara-oceans-science.org/ .
He supervises PhD students, postdoctoral researchers, and trainees in interdisciplinary projects bridging genomics, ecology, and quantitative modeling.
