  • Earth 4D: Subsurface Science & Exploration




Fumio Inagaki is director and principal senior scientist of the Mantle Drilling Promotion Office, Japan Agency for Marine-Earth Science and Technology (JAMSTEC). His research interests are geomicrobiology and biogeochemistry of the ocean, with a special focus on the deep subseafloor biosphere. He uses scientific ocean drilling and the state-of-the-art transdisciplinary approaches to explore the limits of deep microbial life, ecosystem functionality, biogeochemical carbon cycling, geosphere-biosphere interactions, and planetary habitability and sustainability of the Earth and beyond. He was co-chief scientist of IODP Expeditions 329, 337 and 370. He is an associate editor of Science Advances, AAAS since 2019.
