    Masahiro Sugiyama
    Associate Professor, Institute for Future Initiatives

Masahiro Sugiyama is an Associate Professor at the Institute for Future Initiatives(IFI), the University of Tokyo (UTokyo). He holds a Ph.D. in climate science and a master’s degree in technology and policy, both from MIT. Prior to joining UTokyo, he was a researcher at the Socio-Economic Research Center, the Central Research Institute of the Electric Power Industry. He joined UTokyo in April, 2014. An expert on global warming, he has worked on various topics related to climate change, ranging from energy efficiency in global scenarios to citizens’ views on climate geoengineering. His works have been published in various academic journals, including Nature,(http://doi.org/10.1038/531029a).
