Tom Delmont is a CNRS researcher. He explores the genomic diversity of plankton to better understand the ecology and evolution of co-occurring bacterial, eukaryotic and viral lineages abundant in the surface of the oceans. Tom takes advantage of deeply sequenced metagenomes and metatranscriptomes generated by the Tara Oceans consortium, transforming raw reads into manually curated metagenome-assembled genomes and determining their biogeography, functional potential and evolutionary history.
