Gia Khanh Tran, Associate Professor
0 student voices
The Tran Lab studies wireless communication networks that use locations other than the ground, such as drones (UAVs) and satellites. The lab works on millimeter-wave networks between drones, networks that use drones as base stations, and methods for allocating radio resources using AI and reinforcement learning. The lab also studies estimating the positions and sources of radio signals using HAPS, drones, and low Earth orbit satellites. The lab is run together with the Sakaguchi Lab, and the two labs conduct research jointly.

Mana Toma, Associate Professor
0 student voices
The Toma Lab studies how to control light with structures at the nanometer scale in order to create new optical elements and biosensing technologies. The lab combines methods from computational science, nanofabrication, materials exploration, device design, and informatics. It aims to make it possible to perform biosensor measurements, which until now could only be done with dedicated instruments, on familiar devices such as smartphones.

Kenichi Okada, Professor
0 student voices
The Okada Lab studies millimeter-wave radio circuits and analog-digital mixed-signal circuits for next-generation wireless communication. To make millimeter waves usable in familiar devices such as smartphones, the lab builds radios with CMOS integrated circuits, which can be mass-produced at low cost. The lab covers not only circuit design but also antenna and board design, as well as measurements made by actually transmitting radio waves. It advances research and development through industry-academia collaboration with various companies in Japan.

Kenichi Kawabe, Associate Professor
0 student voices
Kawabe Lab studies how to integrate renewable energy while keeping the power system stable. Output from solar and wind power varies with the weather, and their response to faults and other disturbances differs greatly from that of thermal and hydroelectric generation. The lab therefore works on methods for analyzing, operating, and controlling the power grid so that electricity can be delivered reliably. It also keeps in view the use of a variety of technologies that will shape the power systems of the future.

Yukio Tsutsui, Project Professor
0 student voices
Tsutsui-Endo Lab studies ultralight actuators made with new materials for next-generation collaborative robots. It is a joint research chair with YASKAWA Electric Corporation, established across two departments: Electrical and Electronic Engineering and Mechanical Engineering. The lab pursues mechatronics research that crosses the boundary between electrical/electronic and mechanical engineering, in collaboration with many labs inside and outside the university, including the School of Materials and Chemical Technology.

Hideaki Fujita, Professor
0 student voices
The Fujita-Sano Lab researches power electronics, which converts the voltage, current, frequency, and other properties of electricity. Rather than relying on device performance, the lab aims to make power conversion equipment highly efficient, high-performance, and compact through circuit configurations and control methods. Power electronics is used in a wide range of fields, including power generation, power transmission, railways, electric vehicles, and home appliances. The lab is a member of the 'Power Electronics Lab,' which is run jointly by multiple faculty members. The experimental rooms and seminars are shared, while research supervision of students is provided by each faculty member.

Marie Tabaru, Associate Professor
0 student voices
The Tabaru Lab studies "acoustic morphology," which uses sound waves to investigate the shape and properties of materials. The lab focuses on the heterogeneous structures found in many kinds of materials, measuring their shapes and turning them into images. By building ultrasonic devices and systems and carrying out numerical analysis, the lab develops the foundations of measurement technology, aiming for applications in medicine, agriculture, musical instruments, and industry. The lab also conducts joint research with other universities, companies, and physicians.

Jiro Hirokawa, Professor
0 student voices
The Hirokawa Lab studies planar antennas with new structures not found anywhere else in the world. Working with high-frequency radio waves known as microwaves and millimeter waves, the lab has proposed low-loss waveguides and circuits that switch the direction of radio waves. Designed antennas are prototyped at the frequencies where they will actually be used, and verified with measurement facilities specialized for planar antennas, such as an anechoic chamber.

Hiroaki Iino, Associate Professor
0 student voices
The Iino Lab studies large-area thin-film semiconductors for imaging devices such as displays. In particular, the lab focuses on "liquid-crystalline organic semiconductors," in which molecules spontaneously assemble and align. A key feature is that high-quality semiconductor films can be formed even with simple coating methods. The group handles everything from materials development to property evaluation and device applications in-house, with researchers from different backgrounds, such as electrical engineering, chemistry, and physics, working together.

Mutsuko Hatano, Specially Appointed Professor
0 student voices
The Hatano-Iwasaki Lab studies "diamond electronics" using diamond. The lab builds quantum sensors that measure magnetic fields with extreme sensitivity by exploiting the quantum properties of tiny defects inside diamond. The lab also studies quantum light sources and quantum memories for quantum networks. The lab covers everything from materials and physical properties to devices and systems in one integrated effort, aiming to create new value by merging different fields.
