Hiroshi Watabe, Professor
1 student voices
The Watabe Lab conducts research on putting accelerators, radiation, and radioisotopes (RIs) to good use. Its foundation is technology for measuring radiation and knowledge of how radiation behaves inside matter. Using accelerators such as the cyclotron at Tohoku University, the lab works on PIXE analysis, which examines extremely small amounts of elements, and on methods for developing new radiopharmaceuticals used in PET scans. The lab aims to “contribute to people’s health and to a safe, secure society through radiation science.”
Kiyotoshi Sakaguchi, Professor

The Sakaguchi-Satomi-Sueyoshi Lab builds on geomechanics and environmentally harmonious development studies, and aims to build an environmentally harmonious society. The lab studies ways to develop and use underground energy resources, including geothermal energy, and mineral resources in a sustainable manner. To make advanced use of the underground, for purposes such as energy storage and waste disposal, the lab works on measuring crustal rock properties and crustal stress, and on developing the related technologies. The lab also works on building systems of environmentally harmonious construction technology, based on the mechanical interaction between construction and development machinery and soil and rock.
Atsushi Iizuka, Professor

Iizuka-Ho Lab studies technologies for circulating resources and carbon dioxide, as well as technologies for environmental remediation. Using materials such as steel slag and waste concrete, the lab converts carbon dioxide into stable carbonates, leading to its storage and effective use. In water treatment, the lab works with remediation materials made from concrete-based materials and with electrochemical methods that use membranes. It is a relatively new lab, established in April 2023.
Hitoshi Soyama, Professor

The Soyama-Nakai Lab studies the comprehensive evaluation of the integrity and functionality of equipment and structures, with the aim of extending their service life. The core of its work is surface modification that uses the force released when bubbles collapse in water. Because metal can be strengthened simply by treating its surface, without changing the material or its shape, the lab is working to extend the technique to cars, aircraft, and industrial plants. Students can learn, hands-on through experiments, the strength of materials and fluid mechanics that are required for jobs in mechanical engineering.
Takeshi Yamaguchi, Professor

The Yamaguchi-Ishizako Lab studies friction in soft materials such as rubber and biological tissue, as well as human motion analysis. It has been reported that deaths from falls, indoors and outdoors, exceed deaths from traffic accidents. Focusing on the friction between the sole of the foot and the floor, the lab investigates, through both experiments and theory, the conditions needed for stable walking. The lab also covers situations such as baseball pitching, where fingertip friction influences movement and performance.
Toshiaki Nishi, Associate Professor

The Nishi Lab studies the friction of soft materials such as rubber and biological materials. Dry rubber shows high friction, but when water or oil is present, a lubricating film forms at the contact surface and rubber slips more easily. For shoe soles and car tires, keeping friction high even in the presence of liquid has long been a challenge. The lab tackles this challenge by developing techniques for observing contact surfaces, as well as ultra-high-friction surface designs and materials.
Wei Gao, Professor

The Gao-Sato Lab studies ultra-precision measurement and control of the motion and shape of objects, which underpin next-generation manufacturing. Its two pillars are ultra-precision sensors that measure the motion of objects, and ultra-precision control that moves objects. The lab designs how to build sensors that use state-of-the-art lasers, and has recently also been working on ultra-precision sensors that incorporate machine learning. Besides its experiment rooms, the lab has a constant-temperature room for operating ultra-precision measurement and machining equipment, and a workshop for making experimental apparatus.
Hiraku Matsukuma, Associate Professor
0 student voices
The Matsukuma Lab uses state-of-the-art lasers to study ultra-precision measurement of the motion and shape of objects. At the center are the mode-locked femtosecond laser and its frequency spectrum, the optical frequency comb. An optical comb can have its frequency stabilized by synchronizing it with an external frequency standard, and it is characterized by a wide wavelength range and high directionality. The lab uses it as the light source for angle sensors and encoders and studies its application to measurement.
Hironori Tohmyoh, Professor
0 student voices
The Tohmyoh-Kimura Lab takes an interdisciplinary approach to creating new material systems. To take advantage of micro-scale materials with excellent properties and shapes, the lab handles making, joining, examining, and using them as one continuous process. The lab has identified the factors that govern the phenomenon in which passing direct current through the contact between micro-scale materials causes localized melting by Joule heating, making it possible to join materials with high reliability. Its work also extends to studies of hair and nails, and to developing methods that use sound waves and electric current to inspect bonded interfaces and thin layers.
Keiichi Shirasu, Associate Professor
0 student voices
The Shirasu Lab works on circular materials design, dealing with thermoplastics, their composites, and recycled materials. It connects everything from material design through property evaluation, advanced measurement, and simulation, to the making of new materials. Advancing 3D additive manufacturing and direct bonding to dissimilar materials can reduce machining and joining steps. By using synchrotron radiation measurements to understand how resin degrades as it melts and solidifies, the lab aims to build a resource-circulation system with no waste or loss.
