He received Ph.D. in 1995 at the University of Tsukuba, Japan, and has worked as an Assistant Professor at the Institute for Hydrospheric-Atmospheric Sciences of Nagoya University, an Associate Professor at the Hydrospheric Atmospheric Research Center of Nagoya University (1995-2010) and at the Research Institute for Humanity and Nature (RIHN), Kyoto, Japan (2010-2014). He specializes in the fields of ecohydrology and hydroclimatology. His research interests include global warming and the human-nature dimension in Siberia, forest-permafrost-groundwater dynamics, and soil-vegetation-climate interactions in the Arctic circumpolar region. He has been a project leader of the research project (No. C-07) of RIHN, entitled “Global Warming and the Human–Nature Dimension in Siberia: Social Adaptation to the Changes of the Terrestrial Ecosystem, with an Emphasis on Water Environments”. He has co-edited and published three books from Springer, focusing on climate change and social adaptation in northern Eurasia (ISBN:978-981-10-4648-3), groundwater characteristics under current climate condition in Japan (ISBN:978-4-431-54968-0) and on water-carbon dynamics in eastern Siberia (ISBN:978-981-13-6317-7).
