Hiroyuki Uenohara, Professor
0 student voices
The Uenohara Lab studies integrated optical devices and systems for ultrahigh-speed photonic networks. Its goals are high-speed, large-capacity transmission and efficient data transfer with low power consumption. The lab works on techniques that use machine learning to correct distortion in optical signals, as well as silicon photonics optical switches. The lab forms a research group with the Miyamoto Lab and the Koyama Lab, and the groups share student rooms, laboratories, and experimental equipment as needed.

Fumio Koyama, Project Professor
0 student voices
The Koyama Lab studies photonic integrated devices for optical communication networks and sensing systems. At the center of its work is the vertical-cavity surface-emitting laser (VCSEL), which emits light vertically from the surface of a semiconductor. The lab has worked on putting VCSELs to practical use, improving their performance, and applying them to optical communications and sensing. The lab forms a research group with the Uenohara Lab and the Miyamoto Lab, and shares laboratories and experimental equipment as needed.

Shinsuke Miyajima, Associate Professor
0 student voices
The Miyajima Lab studies materials and devices that convert light into electricity, and devices that use them. It works on materials for receivers in optical wireless power transmission, which sends power using blue light, sputtering technology that is gentle on substrates, copper oxide materials, and more. The lab also puts effort into fundamental research on forming thin films by sputtering. The former Yamada Group continues research on chalcopyrite-based materials used in thin-film solar cells.

Akitoshi Okino, Professor
0 student voices
The Okino Lab develops new atmospheric-pressure plasma devices and studies their use in a wide range of fields. It designs and develops diverse plasma devices, from low to high temperature and from small to large, and investigates their properties. The devices are applied in fields such as medicine, dentistry, analysis, life sciences, materials, the environment, and energy. The lab carries out its research in collaboration with the university's School of Medicine and School of Dentistry, as well as many universities, research institutes, and companies in Japan and abroad.

Haruhiko Ito, Associate Professor
0 student voices
The Haruhiko Ito Lab studies "atom photonics," which manipulates atoms with light. Its goal is to control atoms with light to create materials with nanometer-scale dimensions. Because ordinary light cannot be focused finely enough, the lab uses "near-field light," which can be confined to the nanoscale, to manipulate gaseous atoms. The lab designs and builds its own experimental apparatus to suit each research theme.

Nozomi Takeuchi, Associate Professor
0 student voices
The Takeuchi Lab conducts a variety of research mainly using atmospheric-pressure plasma. It aims to realize advanced water treatment and sterilization with plasma, and fast-acting DC circuit breakers. The lab continues research that goes back to elucidating the physics of why phenomena occur, together with the discovery of new applications.

Satoshi Sugahara, Associate Professor
0 student voices
Sugahara Lab studies integrated circuit technology known as VLSI. The lab develops low-energy CMOS technology, centered on memory technology, for use in microprocessors, wearable devices, and more. It also works on transistors based on new operating principles that could benefit future high-performance integrated circuits, and on thermoelectric generation technology that produces electricity from body heat.

Hiroki Kuroda, Associate Professor
0 student voices
Kuroda Lab studies mathematical models and algorithms for solving fundamental problems in signal processing and optimization. Signal processing is the field concerned with extracting high-value information from observed data; removing noise from audio and images is one example. The lab also focuses on applications to real-world problems, centered on wireless communications and remote sensing. A new lab launched in April 2026, it welcomes visits from students who are considering joining.

Sumiko Miyata, Associate Professor
0 student voices
The Miyata Lab researches communication traffic analysis and information security as part of the network infrastructure needed to realize smart cities. The lab also develops mechanisms that use data on the behavior of people and devices to control communication quality more flexibly. The lab started in April 2024, and has also published jointly authored international papers with the University of Glasgow and Loughborough University in the UK.

Kenji Suzuki, Professor
0 student voices
The Suzuki Lab researches computer-aided diagnosis using medical images, and machine learning for image processing and image analysis. Its goal is to build AI that learns, from data and clinical cases, the skills physicians use to read images and make correct diagnoses. The lab works on research in which AI finds lesions in images to assist physicians' diagnosis, and research in which AI learns to identify organs as experienced physicians do. It is the Biomedical AI Research Unit of the Institute of Integrated Research, spanning computer engineering and the biomedical field.
