Prof. Akimasa Sumi Professor and Executive Director of the Transdisciplinary Initiative for Global Sustainability (TIGS) at the University of Tokyo (UT). He started his career serving for the Japan Meteorological Agency and later joined UT, as a professor. His research interest is focused on numerical modeling of weather and climate, especially in the context of global climate change. Recently he led a Japanese team to build the highest-resolution climate model for use with Japan's Earth Simulator, one of the world's best supercomputers. The successful outcome deepened the understanding of climate change, and significantly contributed to the most recent report of the Intergovernmental Panel on Climate Change (IPCC). He was also a Lead Author of chapter 8 of AR4, Working Group I of IPCC. From 1994-2004, he served as Director of the Center for Climate System Research at UT. As the research need on global warming has changed with the changing public awareness, he expanded his research to cover global sustainability, a key concept in addressing climate change. Since 2005, he has been working as the Executive Director in TIGS and promoted researches on various aspects of global sustainability. Currently he also serves as a Member of the Central Environment Council of the Japanese Government.
