Dr. Shunji Kotsuki is a Professor of Institute for Advanced Academic Research (IAAR), Chiba University, and leading environmental prediction science. He received his B.S. (2009), M.S. (2011) and Ph. D. (2013) degrees in civil engineering from Kyoto University. He experienced his professional career as Post-doctoral Researcher (2014-2017), and Research Scientist (2017-2019) at RIKEN Center for Computational Science (R-CCS). He started leading his research laboratory at CEReS, Chiba University since November, 2019. He became to be a Professor of IAAR of Chiba U. since July 2022.

Dr. Kotsuki is a leading scientist on data assimilation and numerical weather prediction with over 10 years of research experience in development of the global atmospheric data assimilation system (a.k.a. NICAM-LETKF). His research interests are in data assimilation mathematics, model parameter estimation, observation diagnosis including impact estimates, satellite data analysis, hydrological modeling, and atmospheric and hydrological disaster predictions. His techniques for ensemble data assimilation have been incorporated in the RIKEN’s global atmospheric data assimilation system, and improved its weather forecasts significantly. The NICAM-LETKF is running operationally as NEXRA since 2017 on the JAXA’s supercomputing system.

He has been recognized by several prestigious awards such as the Thesis Award for Young Scientists from Japan Society of Hydrology and Water Resources Engineering (2013), RIKEN Ohbu Research Incentive Award (2019), Chiba University Award for Distinguished Researcher (2020), and Young Scientist Award of MEXT (2022). In 2017, Dr. Kotsuki was selected as an Excellent Young Researcher by Ministry of Education, Culture, Sports, Science and Technology, Japan. He is also a visiting scientist of R-CCS, and exploring data-driven approaches for the environmental prediction science.
