Kohta Juraku is a professor at Tokyo Denki University (TDU), Japan. He has worked on sociological studies of the governance of risky technologies and the social-learning process from major technological failures. Before joining TDU, he worked at the Department of Nuclear Engineering and Management at the University of Tokyo from 2008 to 2012, during which he spent over a year at the Department of Nuclear Engineering, UC Berkeley as a visiting scholar. He co-organized a series of “social scientific literacy” summer school for engineering students, as well as he was involved in many other activities to promote interdisciplinary collaboration between nuclear engineers and social scientists. He received his PhD from the University of Tokyo for his research on the social-decision making process of nuclear and other energy issues. As a sociologist of science and technology, he has conducted participant observation of nuclear experts’ responses to the Fukushima nuclear disaster both in Japan and US. He has over a decade of experience in collaborative but critical exchange with engineers and practitioners in nuclear and other fields.

Kyoko Sato is Associate Director of the Program in Science, Technology, and Society at Stanford University. Her research examines technoscientific governance in Japan and the United States. At present, she is investigating the dynamics and relationships among global and national nuclear and radiation governance, expertise, and democratic citizenship. She is co-editing a collective volume (with Soraya Boudia and Bernadette Bensaude Vincent), Living in a Nuclear World: From Fukushima to Hiroshima, an interdisciplinary post-Fukushima reflection on the development of the global nuclear order. Her previous work examined interdisciplinary knowledge production in the United States and the politics of genetically modified food in France, Japan, and the United States. She has published in journals such as Science, Technology and Human Values; East Asian Science, Technology and Society; Theory and Society; and 科学技術社会論研究 (Journal of Science and Technology Studies; in Japanese) and book chapters on the 2011 Fukushima disaster both in English and in Japanese. She worked as a journalist in Tokyo before pursuing her PhD in sociology from Princeton University.
