Profile

Born in Hamamatsu City, Shizuoka Prefecture. After graduating from Shonan High School in Kanagawa Prefecture, I entered Nagoya University, Faculty of Agriculture, because while I was passionate on guitar playing in high school I had become eager to study wild lives especially insects that I liked since my childhood. I studied evolutionary ecology using the white butterfly (Pieris rapae) in the laboratory. After graduation, I continued my research on quantitative genetics (a statistical method of evolution) in the lab. In 1991, the doctoral degree of agricultural sciences was endowed from Nagoya University. As a postdoctoral researcher (PD) of the Japan Society for the Promotion of Science (JSPS), I belonged to the National Institute of Genetics, Mishima (1991-1993). Meanwhile, I stayed for half a year as a visiting scientist at the University of Oregon, Department of Ecology & Evolution. As a postdoctoral fellow of NSERC (the Natural Sciences and Engineering Research Council of Canada), I stayed at McGill University, Department of Biology, for two years from 1994. I analyzed evolutionary models based on quantitative genetics. In 1996, I was invited as a visiting associate professor to participate into a research project on risk management of chemical substances (CREST strategic basic research) at Yokohama National University (Japan). As I was interested in the assessment of agricultural chemicals on ecosystems ever since when I was a graduate student at Nagoya University, I decided to work on the research subject to find out the way of evaluating ecological risk of chemicals in terms of extinction risk of species or populations. In 2001 when the project ended, I was fortunately adopted as a faculty member (associate professor) of the School of Economics, Chuo University. Have got professorship in the next year. In 2006, I moved to the National Institute for Environmental Studies, Center for Environmental Risk Research, and resumed researches of environmental risk especially on the ecological risk assessment of various environmental disturbing factors such as chemical pollution, global warming, eutrophication, etc., to ecosystems. From 2011 to 2016, I conducted a research project and developed a computer software to analyze the ecological risk of chemical substances. Since 2016, I am a professor of Graduate School of Global Environment Studies, Sophia University.
