Professor of Biogeochemistry
Field Science Center for Northern Biosphere, Hokkaido University
My research interest involves biogeochemistry, soil and water quality in forest ecosystem. I am recently working on ecosystem functions and services in land systems under changing environments, and on nitrogen footprint assessment as environment indicators of human activities. I am also in charge of Graduate School of Environmental Science for education of graduate students. I am actively involved in International Long-Term Ecological Research Network (ILTER), and Toward INMS (International Nitrogen Management System) project.
