    Masahiro Sugiyama
    Professor, Institute for Future Initiatives

Masahiro (Masa) Sugiyama is a Professor at the Institute for Future Initiatives(IFI), the University of Tokyo(UTokyo). He is an expert on long-term climate policy. His recent research projects include scenario analysis of climate and energy policy and governance of climate engineering from the public engagement perspective. He joined UTokyo in April, 2014. He is a lead author of the Working Group III’s contribution to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change(IPCC). He is a member of Harvard SCoPEx (Stratospheric Controlled Perturbation Experiment) Advisory Committee, and is also a member of the Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) Working Group 41 Ocean Interventions for Climate Change Mitigation. 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.
