[Steps to Regulatory Science]

The research achievements in the field of regulatory science from the beginning of my research are described in an overview. First, I was interested in the complexity of development and pursued my studies on the mechanisms of DNA replication and repair, the mutagenicity of air pollutants, and the oncogene. After researching new phenomena based on the discovery of basic research in molecular/biochemistry, my research interests turned to the field of regulatory science which applies scientific evidence to social systems. I was able to successfully contribute to the field of drinking water quality in Japan through the establishment of drinking water quality standards and standard values, primarily for organic and agricultural chemicals, the development of analysis techniques, and the creation of an organization for ensuring safety. Research on the water quality in public water areas, which are also the sources of drinking water, was another subject in which I was involved. I took part in developing the concept and evaluation methodology for the environmental impact assessment of active pharmaceutical ingredients as well as conducting environmental monitoring on urban rivers in Japan. I have also been engaged in studies on the security and safety of human health with an ecosystem conservation background. It has been a great pleasure to collaborate on research projects with so many people toward a common aim.
