Research Fields/Labs/Faculty

2 Fields, 12 Laboratories, 43 Professors

The College of Geoscience comprises two fields of study: Geoenvironmental Sciences and Earth Evolution Sciences. Geoenvironmental Sciences explore the nature of, and processes in, the atmosphere, hydrosphere and on the Earth’s surface as well as their interaction with human and biological activities. Earth Evolution Sciences study structure, composition, history and mechanics of the Earth by quantitative geological, physical, chemical and biological methods for forecasting the future. Each field has 6 labs, and most labs have multiple professors. The total number of academic staff members is 43.

Geomorphology

Geomorphology is the study of the forms of the land surface, the materials they consist of, and the processes which produce and modify them. Process geomorphology analyses the mechanics of geomorphic processes, whereas historical geomorphology focuses on histories or trajectories of landscape evolution. Applied geomorphology analyses, manipulates, and predicts geomorphic processes, which affect and are affected by human activities. In our laboratory we cover all three approaches by field work, laboratory experiments and analysis using Geographical Information Systems. Our main focus is on landforms related to weathering, landslides, gully erosion, sedimentary processes and ground freezing.

Hydrological Science

Our interests are the water cycle and terrestrial hydrological processes such as rainfall-runoff, evaporation, infiltration into soil, groundwater flow, and so on.  Transport of substances (pollutants, dissolved inorganic compounds, and carbon dioxide, etc.) and their impacts to the environments are also the target of our studies. Field studies are the main tools, but computer models, laboratory experiments are as important to solve hydrological problems.

Regional Geography

Regional Geography reveals the comprehensive man-land relationship from the viewpoint of a specific region while focusing on the socio-economic differences in urban and rural areas. Amid globalization and technological innovation progresses, our regional geography group is engaged in a variety of land-use change issues and subsequent problems in different scales. We are working on empirical analysis for various regions across the world such as Japan, Asia, Oceania, Europe and Americas.

Earth Evolution Sciences

Paleobiological Science

Our research group aims to understand the history of the Earth and life using fossil materials. Through field works and laboratory analyses, we elucidate both global and regional events of organisms in deep time.

Our laboratory covers both micro- and macro-paleontology. Micropaleontology is a study of microscopic fossils, such as fossil plankton, pollen, and conodonts. Dr. Sachiko Agematsu especially focuses on conodonts, which are an enigmatic animal group that diversified in Paleozoic, along with other microfossils. By establishing conodont taxonomy and biostratigraphy, Dr. Agematsu is aiming to understand life history in ocean, such as mass extinction events in Phanelozoic and paleozoogeography from Paleozoic to today.

Dr. Kohei Tanaka, on the other hand, studies macro-paleontology. His specialty is fossil vertebrates (i.e., animals with back bones), particularly dinosaurs. Dr. Tanaka’s main projects include evolution of reproductive strategies in the lineage of reptiles, dinosaurs, and birds, using fossil eggs, nests, and babies.

Mineralogy

A mineral is a naturally occurring solid with a highly ordered atomic arrangement and definite but not fixed chemical composition. Studying minerals involve various aspects of sciences and industrial applications. The study that reveals physical properties of minerals is fundamental to a deeper understanding of the Earth's past, present, and future. The application of inorganic chemistry to industry such as photonic crystals, functional materials, and semiconductors brings about an affluent society and hopeful future in the world. We welcome students with backgrounds in geology, physics, chemistry, and materials science.
