The Center for Mathematical Science and Advanced Technology (MAT) explores "mathematical science" for the rigorous understanding of the ocean, earth, and life, and drives the development of "advanced technology" that enables their sophisticated and appropriate utilization.

Our research primarily encompasses the diverse problems situated within the discipline of classical physics, such as fluids, solids, heat, and electromagnetism. We challenge these problems using mathematical science and computational science as our core methodologies.

Research themes span a wide range, from synchronization phenomena appearing between distant locations, mantle convection and plate motion of the Earth and other planets, swimming simulations of fish schools, magnetohydrodynamic simulations, statistical properties of turbulence, or nonlinear physics of granular materials, large-scale high-performance computation on the scale of billions of particles, and multiphase fluid simulations consisting of fine powder and liquid, to micro-meteorological simulations spanning from cloud particle generation to urban scales, and further to the science of "shapes" appearing in multiphysics phenomena, mathematics of curved origami, detection of traces of high-energy particles remaining in minerals, and the reconstruction of classical physics based on discrete manifold theory. This diversity, which at first glance may appear divergent, is the essence of MAT, decoding all phenomena through the common language of mathematical science.

We employ "mathematical science" to reduce complex phenomena into rigorous mathematical models, and utilize "computational science" to tackle those mathematical problems using advanced computational scientific methods. Of the three pillars of scientific methodology—experiment, theory, and computation—we have focused on developing original theoretical and computational frameworks. MAT will continue to develop new methodologies in theory and computation, remaining dedicated to the challenge of elucidating the various phenomena of the ocean, earth, and life.

Meanwhile, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has accumulated unparalleled observation and experimental data. In recent years, "data science," symbolized by generative AI, has been achieving breakthrough development as the "fourth pillar" of science. Drawing upon its accumulated expertise in "theory and computation," MAT will advance the theoretical foundations of data science and develop innovative methodologies to generate novel scientific value from JAMSTEC’s proprietary datasets.

Generating novel scientific insights into the ocean, earth, and life through the continuous development of methodologies in theory, computation, and data science—this defines our vision for the next stage of research and development.
