Ryo Ishikawa, Professor
0 student voices
The Ishikawa Lab studies the hardware technologies that support wireless information and communication. The lab works on microwave-band semiconductor circuits that are ultra-high-efficiency, low-distortion, and wideband, as well as techniques for evaluating microwaves with high precision. The lab also develops filters, antennas, and MMICs for UWB, a next-generation ultra-high-speed short-range wireless system. The lab also conducts exploratory research in nanotechnology, such as ultra-high-sensitivity photodetectors using quantum wires.

Koji Ishibashi, Professor
0 student voices
The Ishibashi Lab researches wireless communication technologies under the banner of Ultimate Reliability of communications. Prof. Ishibashi's current research interests are robust beamforming, grant-free access, energy harvesting, compressed sensing, coding, cell-free networks, and MIMO. The lab also takes part in joint projects with universities and companies. Students work on topics such as near-field beamforming, cell-free systems, and waveform design for terahertz-band communication.

Gongke Fan, Professor
0 student voices
Fan Lab provides education in the design, implementation, and evaluation of hardware systems and VLSI. The lab integrates various kinds of information processing hardware, aiming to realize a system on chip. Developing high-performance arithmetic circuits that can be realized with few elements is also one of its research topics. Students build and run dedicated hardware that processes multimedia data such as images and audio, and verify it in practice.

Keisuke Hosokawa, Professor
0 student voices
Hosokawa Lab studies variations in the ionosphere, a region of Earth's upper atmosphere, using light and radio waves. The ionosphere is the region where the International Space Station and many polar-orbiting satellites fly. Because it also strongly affects the radio waves used for satellite communication and satellite positioning, the lab considers it important to understand its behavior in detail. The lab investigates variations in the ionosphere and aurora through radio wave observations and high-speed camera imaging of aurora. Observations are carried out in Japan as well as in places such as Northern Europe and Alaska.

Takeo Fujii, Professor
0 student voices
Fujii Lab studies how to advance mobile communications, such as mobile phones and wireless LANs, from a variety of perspectives. As wireless systems multiply and frequency bandwidth runs short, the lab studies topics such as cognitive radio, which recognizes the surrounding radio environment and uses bands that are not being effectively utilized. Wireless ad hoc networks, in which terminals autonomously form a network among themselves, and wireless protocols, which define the rules of transmission procedures, are also research topics. As a lab policy, students carry out world-class research from their fourth year of undergraduate study.

Jun Suzuki, Associate Professor
0 student voices
The Suzuki Lab studies a variety of problems, centered on theoretical physics, quantum information theory, and mathematical statistics. The lab works on quantum information theory, quantum estimation theory, and quantum information geometry, aiming to move from fundamental theoretical research to applications that can be verified in experiments. Research is centered on analysis with pen and paper, with numerical computation on computers when necessary. A page explaining lab assignment for graduation research in Reiwa 8 (FY2026) is available.

Shunji Sato, Associate Professor
0 student voices
The Sakaguchi-Sato-Aiba Lab views the human brain as an "information processing system" and aims to elucidate brain function by considering what computations take place inside it. To investigate how vision works, Associate Professor Shunji Sato describes mathematically the behavior of neurons involved in visual information processing and simulates it on a computer. Associate Professor Eriko Aiba studies the mechanisms by which skills are acquired, focusing in particular on musical instrument performance and investigating it with attention to the auditory periphery. On the lab website, the Sakaguchi Lab, Sato Lab, and Aiba Lab are listed side by side on the same research introduction page.

Soichi Ando, Associate Professor
0 student voices
The Health and Sports Science Lab studies what happens in the human body when we exercise. Covering everything from a single bout of exercise to long-term exercise, the lab examines changes ranging from the skeletal muscles and the respiratory and circulatory systems to cognitive performance, mood, and changes in brain function and structure. The lab studies not only exercise performed by one's own will, but also the body's responses to electrical muscle stimulation (EMS) of the skeletal muscles. Mainly in joint research with other universities and research facilities, the lab uses measurement devices such as positron emission tomography (PET), (functional) magnetic resonance imaging (MRI), and electroencephalography (EEG).

Tomonori Sadamoto, Associate Professor
0 student voices
The Sadamoto Lab conducts interdisciplinary research that combines control-theoretic machine learning with power engineering. Theoretical research means presenting methodologies for solving problems together with their justification, for example by proposing and verifying algorithms or by giving mathematical answers to problems. Recently, the lab has been working on new data-driven control methods (including reinforcement learning) and on international research aimed at solving social issues such as smart grids. At present, most of the research is completed through mathematics and simulation, and the lab conducts almost no experiments.

Kiminao Kogiso, Professor
0 student voices
The Kogiso Lab studies mechanisms and methods for skillfully controlling the "motion" of objects and people. In control engineering, the motion and mechanisms of a target are turned into a mathematical model from data or physical equations, and a control method that satisfies the required specifications is designed. The professor works on encrypted control, control of artificial muscles, control of decision-making, and control of constrained systems. The lab also aims to carry out joint research with companies and others, and to open up new areas of applied control research.
