(New Caledonia, 2013)

An ecologist working on nonlinear time-series analysis, soil microbial community, plant-soil feedbacks and environmental DNA

What's New


Appointed as a project-specific associate professor at Hakubi Center, Kyoto University.


A collaborative paper on "core microbiomes" in agroecosystems has been publihed in Nature Plants. This perspective paper proposes a framework to understand and utilize complex microbial communities in agroecosystems.
