Susumu Kitagawa obtained a Ph.D. degree from Kyoto University. He is a distinguished professor at Kyoto University Institute for Advanced Science (KUIAS) and Director of the Institute for Integrated Cell-Material Sciences (iCeMS), Kyoto University. He originated the science and technology of gas with porous coordination polymers (PCPs) and metal-organic frameworks (MOFs). He predicted early on the softness of PCP/MOF crystals and demonstrated that their framework changes in response to external fields to express various functions such as storage, separation, and conversion. He named these materials soft porous crystals (SPC) as a more generic term and pioneered chemistry, which is now rapidly spreading to other porous materials. He showed a clear vision for research by categorizing PCP/MOF materials as evolving from the first- to second-generation type in the early days to the third-generation in SPC and now to the fourth-generation type. He has advocated that the 21st century will be the "age of gas," where gas will be a crucial material in all areas of the environment, energy, resources, and health, and porous materials will play an important role. He received the Japan Society of Coordination Chemistry Award (2007), Humboldt Research Award (2008), The Chemical Society of Japan Award (2009), Thomson Reuters Citation Laureate (Chemistry) (2010), The Medal with Purple Ribbon, Japanese Government (2011), The RSC de Gennes Prize (2013), The 10th Leo Esaki Prize (2013). Japan Academy Award (2016) and ACS Fred Basolo Medal (2016), The 58^th Fujihara Award (2017), Chemistry for the Future Solvay Prize (2017). Thomson Reuters and Clarivate Analytics Highly Cited Researcher (2014 - 2022).
