I worked at Kyoto University from 1975 to 1977. Then I moved to the National Institute for Environmental Studies at 1977. I spent more than 30 years in NIES studying various environmental problems, such as eutrophication of lakes, soil degradation, and depletion of groundwater resources. I moved again to Sophia University at 2009 and have worked there since then.
Through my research period, I have striven to understand these problems from the perspectives of transport and movement phenomena, conducting field surveys and many experiments to understand the mechanisms of the phenomena, and constructing the models to simulate the phenomena.
From 1994 to 2005, I participated in the activities for creating international research networks for global environment changes at the Center for Global Environmental Research, NIES, and the Ministry of the Environment. Through these activities, I really felt a need for cooperation between natural scientists and social ones; therefore, I endeavored to involve researchers from many universities in the land use/cover change research project which required the integrated approached of the both scientists for seeking the ways of sustainable societies.
My major research topics are as follows:
1975-1977: Mechanisms of local scouring around bridge piers.
1978-1985: Mechanisms of re-suspension of cohesive bottom sediments in shallow lakes.
1986-1991: Mechanisms of infiltration of water in unsaturated soil conditions
1992-2000: Land use/cover change in China
2001-2008: Depletion of groundwater resources at the Hebei Plain in China
2008- : Projection of population distribution in China at 2030
