Kosuke Shiraishi is an Assistant Professor at Kyoto University and conducts research on C1 microbes that can utilize reduced carbon sources like methane and methanol. He advocates "C1 Chem-Bio Economy", a concept that balances economic growth and environmental measures, based on the new carbon cycle where classical carbon cycle between biomass-CO2 and methane cycle between methane-CO2 are conjugated. Apart from the academic research, he contributes to science-policy dialogues including UN-FAO Microbiome Working Group, IBF Food Systems Microbiome Working Group and Committee of Young Experts Towards Carbon Neutrality in 2050 of the Japanese Ministry of Economy, Trade and Industry. Before joining Kyoto University, he worked for the UN-FAO and Japanese Ministry of Foreign Affairs. More information is available at
