Biography
Muneta Yokomatsu is a senior research scholar jointly associated with the Systemic Risk and Resilience Research Group of the IIASA Advancing Systems Analysis Program and the Equity and Justice Research Group of the IIASA Population and Just Societies Program. He first joined IIASA as a guest research scholar in March 2018, and after having participated in several projects as an associate research scholar, took up his current position in April 2022.He received his Bachelor’s, Master’s, and PhD degrees from Kyoto University, Japan. He started his career at Tottori University in Japan as a research associate in 2001. He moved to the Disaster Prevention Research Institute at Kyoto University as an associate professor in 2005 and worked there until March 2022. He has held and continues to hold visiting fellow positions at several universities including as a visiting researcher at the University of Minnesota in the US (2008-2009), Waseda University in Japan (2008-present), the University of Tokyo, Japan (2018-present), and as visiting associate professor at the University of Tokyo (2008-2012).
His research fields include the economic analysis of climate-related risk management, where he has developed methods of cost-benefit analysis of disaster prevention and infrastructure provision; and social network analysis, where he has focused on the dynamics of network formation of people in a local community. He is now intensively working on simulation models of macroeconomic dynamics of climate-change-related natural hazards and exploring the impacts of risk reduction policies.
