Our research is focused on the discovery of novel bacterial, archaeal and eukaryotic microbes and viruses in environmental sequence data. We use multi-omics (metagenomics, metatranscriptomics, single cell genomics and phylogenomics) and machine learning to identify new divergent lineages and expand the Tree of Life. We then investigate the coding potential to find novel functions that may impact microbiome structure and biogeochemical cycles.

| More about Frederik. | Tomas uses traditional cultivation methods along with microscopy and genomics to study endosymbiotic associations within microbial eukaryotes. He hopes to broaden our understanding of the roles these associations play in the evolutionary history of life. | Juan uses approaches at the interface of evolutionary genomics and systems biology to discover novel microbial lineages, predict their lifestyle, and investigate their effects on the environment | Clarence identifies and analyzes novel clades of RNA viruses and determines novel viral gene functions that may impact hosts and host populations. |

| Marianne uses metagenomics to study giant viruses in cold marine environments and is interested in analyzing genes that can impact the metabolism of their hosts. | Miguel is looking for previously uncharacterized lineages of protists using molecular phylogenetics, genomics, and metagenomics. His aim is to understand the phylogenetic and metabolic diversity that these novel taxa harbor and how they have been shaped by the environment. | Petra cultivates marine algae infected by giant viruses from subtropical, oligotrophic ocean gyres. She uses genomic and transcriptomic sequencing along with laboratory manipulations to understand how nutrient stress impacts virus-host interaction. |
