With regard to various environmental problems, such as eutrophication of lakes, soil degradation, and depletion of groundwater resources, I spent more than 30 years at NIES striving to understand these problems from the perspectives of transport and movement phenomena, conducting experiments to understand the mechanisms of the phenomena, and constructing models for the reproduction of 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.

I am in charge of teaching the following four courses: Global Environmental Engineering, Disposal of Industrial Waste, Movement Phenomena and the Environment, and Environmental Engineering. I am also the coordinator for Frontiers of Environmental Research, a series of lectures delivered by the front-line researchers in NIES. Although my courses are categorized as natural science and engineering field, I aim to provide the lectures so that the students with social science backgrounds can understand them. I would be glad if, after learning in my courses, the students are interested in understanding the causal relationship between human activities and environmental problems from a natural sciences perspective.

In my seminar, I would like to provide the knowledge and information of various environmental issues in order for the students to find their research themes themselves. Some of them may prefer to conduct the research of natural science. In this case, I would coordinate to have them taken the instruction from the researchers of NIES.
As the students in my seminar may have various research backgrounds, I have encouraged them to aim at learning mutually many methods to understand various environmental problems rather than gathering alone the knowledge of a specific field. I believe that every method for solving environmental problems can be determined by both the logic from the natural sciences and the social consensus.
In my seminar, taking up several specific topics which the students are interested in, reading textbooks and other materials on them, we discuss issues  from different perspectives.
