Tsuyoshi Iizuka, Associate Professor
Earth & Climate2 student voices
The Iizuka Lab uses the methods of cosmochemistry, geochemistry and isotope science to study the formation and evolution of the planets in the solar system. The lab analyzes the chemical elements and isotopes contained in terrestrial rocks and meteorites to investigate how the Earth and other planets have evolved. Students from a wide range of fields, including earth science, physics and chemistry, come together across disciplinary and university boundaries. Research proceeds through discussion, both between the professor and students and among the students themselves.

Yusuke Yokoyama, Professor
Earth & Climate2 student voices
The Yokoyama Lab uses geochemical methods to study climate change and shifts in the marine environment, mainly over the past 2 million years. The lab analyzes records preserved in coral skeletons, ice cores, tree rings, and sediment cores from the seafloor and lake bottoms. It determines when these records were formed by dating them with accelerator mass spectrometry (AMS). Its main themes are environmental change in Antarctica, environmental change in the mid- and low latitudes, solar activity and variations in the Earth's magnetic field, and changes in the solid Earth and the evolution of the surface environment.

Takashi Mikouchi, Professor
Space, Particle Physics & Aerospace1 student voices
Mikouchi Lab studies the formation and evolution of solid materials from the birth of the solar system to the present, as well as the principles governing planet formation and internal evolution. The lab examines meteorites and lunar rocks using analytical methods for very small areas, such as scanning and transmission electron microscopy and X-ray diffraction. A distinctive feature of the lab is that it treats the solid materials found in the Earth, planets, and meteorites as minerals, focusing on their crystal structures and textures and on how these relate to the conditions under which they formed. The lab carries out joint projects with many research institutions abroad, including NASA's Johnson Space Center in the United States.

Yoshio Takahashi, Professor
Earth & Climate1 student voices
The Environmental Geochemistry Lab studies "molecular geochemistry," an approach that understands phenomena on Earth through chemical reactions at the atomic and molecular level. The lab deals with material cycles in every kind of environment, including the atmosphere, water, soil, organisms, rocks, human activities, and even extraterrestrial materials. It seeks to understand, at the atomic and molecular level, which chemical reactions underlie the visible macroscopic phenomena. From there, the lab aims to accurately understand and predict Earth's past, present, and future.

Aki Takigawa, Associate Professor
Space, Particle Physics & Aerospace1 student voices
Takigawa Lab studies the minerals in dust drifting through space to research the raw materials of the solar system. At the end of their evolution, stars release large quantities of fine mineral and organic grains into interstellar space, along with gas. Those grains become the raw material for the next generation of stars and planetary systems, and the solar system, formed 4.6 billion years ago, was born from them as well. By combining meteorite analysis and experiments with observations of stars, the lab aims to clarify the place of the solar system within the Milky Way Galaxy.

Itai Takaaki, Associate Professor
Earth & Climate1 student voices
The Itai Lab studies how trace elements move through the environment, using geochemical methods. Specializing in the behavior of toxic metals such as arsenic and mercury, the lab has conducted research in Asia, Africa, and the open ocean. At the University of Tokyo, the lab is placing greater emphasis on research in inland waters such as lakes and rivers. The lab aims to re-examine the natural environment of the Japanese Archipelago from a geochemical perspective and to renew our understanding of elemental cycling.

Takenori Sasaki, Associate Professor
Bio & Life Sciences0 student voices
The Sasaki Lab studies animal taxonomy, paleontology, and comparative anatomy. Focusing mainly on mollusks (shellfish), the lab investigates them from four perspectives: species diversity, body plan diversity, habitat diversity, and the fossil record. By comparing forms, the lab aims to understand the meaning of the shapes of living things and how they came to be. The lab is located in the University Museum, where Associate Professor Sasaki is in charge of managing the museum's paleontological and zoological specimens.

Hirata Takafumi, Professor
Earth & Climate0 student voices
Hirata Lab studies the concentrations and isotopic compositions of trace elements contained in rocks and meteorites. These measurements make it possible to estimate when a sample formed and what the environment was like at that time. Using state-of-the-art analytical instruments, the lab aims to clarify the history of the solar system, the Earth, and the origin and evolution of life. Visitors are welcome to tour the lab at any time, and if you contact the lab in advance, someone will show you around.

Hiroyuki Kagi, Professor
Earth & Climate0 student voices
The Kagi Lab aims to understand the materials that make up the Earth, and the processes by which they change, from a chemical perspective. Making use of techniques that allow in situ measurement while high pressure is maintained, the lab investigates the structures and transformations of various materials under high pressure. The lab takes on a wide range of research topics, centered on spectroscopy and crystallography under high-pressure conditions corresponding to the Earth's deep interior. The lab is open to recruiting students who are interested in geochemistry and high-pressure science, and accepts inquiries about lab visits at any time.

Tatsuya Hirasawa, Associate Professor
Bio & Life Sciences0 student voices
The Hirasawa Lab combines paleontology and evolutionary developmental biology to study the evolution of animals with backbones (vertebrates). The fossil record shows that the forms of living things have not changed at a uniform rate, but have repeatedly alternated between periods of stasis and periods of abrupt change. The lab investigates the reasons for this pattern from two sides: external factors such as environmental change, and internal factors in the form of developmental constraints, which arise from how the body is built. Centered on detailed analysis of fossil specimens and developmental biology experiments at the gene and cell level, the lab also carries out fieldwork to collect fossils and international collaborative research.
