Hiroyuki Tanaka, Professor
Earth & Climate0 student voices
The Tanaka Lab studies the Earth's interior using highly penetrating, high-energy elementary particles such as muons and neutrinos. It is both an old and a new field, combining geophysics and particle physics. The lab has developed a technique called muography, which uses cosmic-ray muons to look inside mountains, faults, and the Earth's interior. The lab was a world pioneer in demonstrating imaging of the Earth's interior with this method.

Masao Nakatani, Professor
Earth & Climate0 student voices
The Nakatani Lab studies the mechanisms by which earthquakes occur through experiments and theory on rock friction and fracture. It investigates, from both physical and chemical perspectives, how friction changes over time when faults rub against each other. The lab deploys detectors that capture tiny fractures deep underground in South African mines, and has found fracture activity concentrated on faults and changes in that activity before large earthquakes. Another line of research uses statistics to test how reliable phenomena regarded as earthquake precursors actually are.

Kiwamu Nishida, Professor
Earth & Climate0 student voices
The Nishida Lab studies the vibrations of the Earth that continue even when no earthquakes are occurring. By carefully analyzing records from many seismometers, barometers, and water pressure gauges, the lab searches for new vibration phenomena hidden in records that were previously dismissed as noise. The lab investigates how ocean waves and the atmosphere shake the Earth, treating the atmosphere, oceans, and solid Earth as one large integrated system. The lab also uses these vibrations to study the structure of the Earth's interior and how it changes over time.

Takehiko Hiraga, Professor
Earth & Climate0 student voices
The Hiraga Lab studies the Earth as a mixture of solid and liquid, and as rock made up of aggregated mineral grains. In the laboratory, the lab synthesizes rocks and analyzes their structure and chemical composition, especially at the nanoscale. By combining deformation experiments, high-temperature creep experiments, theoretical modeling, and electron microscope observation, the lab investigates phenomena that occur inside the Earth. The lab has accepted students from a variety of fields, including seismology and petrology, and also welcomes students who have studied materials science.

Kazutaka Katoh, Professor
Bio & Life Sciences0 student voices
The Katoh Lab studies bioinformatics techniques rooted in molecular evolution. The lab continues to develop MAFFT, software that computes multiple sequence alignments, which line up gene or protein sequences for comparison. In parallel, the lab also carries out molecular evolutionary sequence analyses using MAFFT and other tools. While seeking a good balance between biological interest and practical need, the lab has worked for many years on important, long-standing problems.

Fumi Egusa, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Egusa Lab studies how gas moves and how stars form in spiral and barred spiral galaxies. The lab belongs to the Radio Astronomy Group at the Institute of Astronomy, and its observations center on ALMA, which operates in the Atacama highlands of Chile. Using the spectral lines of molecules and atoms visible at radio, millimeter, and submillimeter wavelengths, the lab investigates the interstellar medium of galaxies. The lab is also pursuing statistical studies that compile large numbers of molecular clouds in nearby galaxies and in the Milky Way.

Itsuki Sakon, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Sakon Lab studies what cosmic environments were needed before humans could emerge on Earth, and how common such conditions are. Heavy elements such as carbon and nitrogen, produced over the course of a star's life, are scattered into their surroundings when the star dies, chemically enriching the universe. The lab's main methods are infrared observation from the ground and from satellites, and laboratory astrophysics, in which cosmic dust is made in the laboratory. The lab does not limit itself to particular methods; it tries to move one step at a time toward an answer to this question from every possible angle.

KWON Jungmi, Associate Professor
Space, Particle Physics & Aerospace0 student voices
The Kwon Lab studies how stars, planetary systems, and exoplanets form and evolve. The lab carries out polarimetric observations at multiple wavelengths, which can map the structures around stars and the shapes of magnetic fields. By systematically conducting circular and linear polarization surveys, the lab also investigates the origin of the homochirality of life. The lab also develops polarimetric instruments to be mounted on ground-based and space telescopes, and works on astrobiology experiments.

Kotaro Kohno, Professor
Space, Particle Physics & Aerospace0 student voices
The Kohno Lab uses millimeter and submillimeter observations to study how galaxies, the groups they form, and the massive black holes within them were born and have evolved. The lab belongs to the Radio Astronomy Group at the Institute of Astronomy. Centered on ALMA, it also combines data from optical, infrared, and X-ray telescopes in its investigations. The lab is also developing line intensity mapping, a new observational technique, along with the instruments and data analysis methods it requires. Whether a student's focus is observation or instrument development, the lab's basic policy is for each person to pursue the research they want to do as thoroughly as possible. Associate Professor Fumi Egusa, who belongs to the same group, studies how gas moves and how stars form within spiral and barred spiral galaxies.

Takashi Miyata, Professor
Space, Particle Physics & Aerospace0 student voices
The Miyata Lab studies methods for observing the universe in mid-infrared light. Mid-infrared light is emitted by relatively cool matter, which makes it well suited for observing the surroundings of newborn stars and the dust released by dying stars. The lab handles everything itself, from developing observing instruments to carrying out observations, and is building instruments to be mounted on the telescope at the University of Tokyo Atacama Observatory (TAO) in Chile. Ground-based telescope projects run for a shorter period than space telescope projects, so undergraduate and graduate students can take the lead in the research.
