Yoshiyuki Tanaka, Associate Professor
Earth & Climate0 student voices
The Tanaka Lab studies geodesy, the science of precisely measuring changes in the Earth's shape and gravity. Through observations of crustal deformation and gravity and through numerical simulations, the lab investigates everything from global-scale changes to the mechanisms of plate boundaries. The lab covers a wide range from observation to theory, so students can do research in the way that suits them best, whether that means collecting data in the field, programming, or building theory with mathematics.

Kawai Kenji, Associate Professor
Earth & Climate0 student voices
The Kawai Lab studies the structure of the Earth's interior by analyzing records of earthquake shaking (seismic waveforms). Its main theme is investigating the deep Earth near the core-mantle boundary using a method called waveform inversion. The lab's research spans multiple fields, from interpreting seismic waves based on the properties of minerals, to the science of mineral friction, to the planetary geology of Mars and the Moon. The lab has also carried out fieldwork in regions with limited data, such as deploying an array of seismometers in Thailand.

Ryosuke Ando, Associate Professor
Earth & Climate0 student voices
Ando Lab studies the mechanisms of tectonics, including earthquake generation. The lab aims to build a comprehensive framework for understanding how stress accumulates on faults until they rupture, and how Earth's interior and surface deform. In many of its studies, the lab uses numerical computation to explain a wide range of observational data in terms of fundamental physical components. To reconstruct past earthquakes preserved in strata and landforms, the lab also conducts field surveys and develops new analysis methods.

Yasuko Takei, Professor
Earth & Climate0 student voices
Takei Lab studies the properties of rocks inside the Earth and the dynamics of Earth's interior. Rock is a polycrystalline material made up of many mineral crystals. Under the high temperatures and pressures found inside the Earth, the behavior of atomic-scale defects governs the properties of the rock as a whole. Through experiments on low-melting-point "analog" polycrystals combined with theory, the lab aims to explain the large-scale behavior of rocks from their microscopic mechanisms.

Kei Hirose, Professor
Earth & Climate0 student voices
The Hirose Lab studies the true nature of Earth's deep interior and how planets form, using a method called ultrahigh-pressure and high-temperature experiments. Using a device called a diamond anvil cell, made with natural diamonds, the lab creates conditions of pressure and temperature that exceed those at the center of the Earth, and can synthesize any material found inside the Earth in the laboratory. In addition to phase transitions of materials in the deep mantle and core, the lab investigates the speed at which seismic waves travel, how easily electricity and heat are conducted, how materials melt, and how elements separate from one another. Even undergraduate and master's students can take on challenges in world-leading research.

ウォリス サイモン, Professor
Earth & Climate0 student voices
The Rock Structure and Tectonics Group combines the methods of structural geology and petrology to study how mountains form (orogenesis) in subduction zones and continental collision zones. The lab pays particular attention to the relationship between rock deformation and metamorphism, in which rocks are transformed by heat and pressure. Drawing also on results from other fields such as seismology, the lab is interested in clarifying mantle flow and the mechanisms by which slow earthquakes occur. The lab conducts field surveys in the Sanbagawa belt of Japan, as well as in the western United States, the Andes, the Tibetan Plateau, and the European Alps.

Satoshi Ide, Professor
Earth & Climate0 student voices
Ide Lab studies the mechanisms of earthquakes as a physical phenomenon. The lab clarifies the diverse properties of earthquakes, from large to small and from fast to slow. It aims to explain the complexity and diversity of earthquakes with physical laws that are as simple and realistic as possible, and to improve future predictions.

Hiroya Yamano, Professor
Environment & Sustainability0 student voices
The Yamano Lab studies coastal zones such as coral reefs, focusing on how global environmental change affects landforms, ecosystems, and human society. The lab deals with global environmental change in the Holocene and the Anthropocene, assessing and predicting its impacts and exploring measures for adapting to the changes. Its research methods are on-site field surveys and spatial data analysis. The lab aims to understand the connections among the global environment, living organisms, and human society, and to conduct research that contributes to building a sustainable society.

Eiichi Tajika, Professor
Earth & Climate0 student voices
The Tajika Lab studies how the surface environments of Earth and other planets formed and have changed over time, and how these changes relate to the origin, evolution, and extinction of life. The lab focuses in particular on large-scale environmental changes linked to mass extinctions, such as global glaciation (Snowball Earth), asteroid impacts, and oceanic anoxic events. Its main method is numerical simulation using climate models and biogeochemical cycle models, and it also takes part in collaborative research involving field surveys and chemical analysis. Building on these findings, the lab investigates the conditions for habitable planets, including Mars, Venus, and planets outside the solar system.

Masayuki Ikeda, Associate Professor
Earth & Climate0 student voices
The Ikeda Lab studies how Earth's environment and life have influenced each other throughout geological time. In particular, it investigates how changes in insolation drive climate change, and how this relates to the extinction, adaptation, and evolution of dinosaurs, plants, and other organisms. The lab has also continued research on reading Milankovitch cycles from the striped patterns of bedded chert, a stratum formed in the deep sea. Through fieldwork, geochemical analysis, and analysis of the fossil record, the lab aims to uncover the causes and actual nature of major environmental changes in Earth's history.
