Dr. Mikio Sakai is a Full Professor in the Department of Nuclear Engineering and Management at The University of Tokyo and an internationally recognized leader in Discrete Element Method (DEM) and particle-resolved simulation of granular and multiphase flows. He received his Ph.D. from The University of Tokyo in 2006 and joined the university as an Assistant Professor in 2007, was promoted to Associate Professor in 2008, and to Full Professor in 2023. Professor Sakai has established a strong international presence through long-standing collaborations and visiting appointments, including Imperial College London (Visiting Reader, 2016-2023; Visiting Professor, 2023-present) and the University of Surrey (Visiting Professor, 2019-2025). His research focuses on high-fidelity modeling and simulation of granular and multiphase flows, large-scale parallel computation, and data-driven computational mechanics, including AI-based surrogate modeling and data science approaches for powder and particle systems. He is widely regarded as one of the leading experts in computational granular dynamics, and his work has significantly advanced the predictive capability of discrete element, continuum, and hybrid multiscale methods for industrial and geophysical particulate systems. Professor Sakai has delivered numerous invited and keynote lectures at major international conferences and has received several prestigious awards in recognition of his scientific contributions, including the SCEJ Award for Outstanding Research Achievement (The Society of Chemical Engineers, Japan), the IP Award (Information Center of Particle Technology), and the JACM Computational Mechanics Award (Japan Association for Computational Mechanics). He plays a prominent leadership role in the international powder and particle technology community. He served as Chair of the 10th International Conference on Discrete Element Methods, is a Director of the Society of Powder Technology of Japan, Head of its Modeling and Simulation Division, and Chair of the AI Technical Committee of the Association of Powder Process Industry and Engineering, Japan. He currently serves as an Editor for Chemical Engineering Science and Granular Matter, and as an Associate Editor of Powder Technology.
