RIKEN Center for Integrative Medical Sciences Laboratory for Microbiome Sciences
Team Leader: Hiroshi Ohno (M.D., Ph.D)
Research Summary

The aim of the microbiome research team (Laboratory for Microbiome Sciences) is to comprehensively elucidate the host-microbial interaction by the analysis of the ecological, functional, and medical features of the microbial communities such as human gut, oral, skin microbiomes, and various symbiotic communities in other species. Our team also develops technologies of bioinformatics and statistics for the analysis of large metagenomic and genomic datasets of microbiomes and microbes produced by the next-generation sequencers.
