Hiroshi Kikuchi, Associate Professor
0 student voices
The Kikuchi Lab centers on developing remote sensing technology for meteorological phenomena, and researches the development of next-generation weather radar and the analysis of observation data on cumulonimbus clouds. The lab focuses on phased array radar, which can observe in fine detail up to high altitudes at short time intervals, and aims to contribute to the prevention of weather-related disasters. The lab also works on developing an observation system that pinpoints the positions of lightning discharges in three dimensions. The lab conducts its research together with the members of the Center for Space and Electromagnetic Environment Research.

Yoshiki Kayano, Professor
0 student voices
The Kayano Lab studies electromagnetic compatibility (EMC), the discipline of enabling electronic devices to coexist and operate in complex electromagnetic environments. Devices that use high-frequency electrical signals, such as computers, can radiate unwanted electromagnetic waves and interfere with other devices. Working closely with the Xiao Lab in the same EMC field, the lab investigates how high-frequency signals propagate and how unwanted electromagnetic waves are generated, through both experiments and simulation. The lab treats EMC problems on and around printed circuit boards as fundamental research, using simplified models to clarify the basic phenomena.

Kazuki Nishi, Associate Professor
0 student voices
The Nishi Lab studies the theory and algorithms of signal processing, which extract target information from signals obtained from images, audio, and various measurements. Currently, the lab focuses on methods for testing camera performance and quality, and develops techniques for measuring vibration, resolution, and more. Its research themes are vibration measurement of tripods and shutters, precise resolution measurement, and measurement of camera optical axis distortion. Some of these techniques have already been put to practical use, and the lab aims to develop technology that people actually use.

Hideyuki Nomura, Professor
0 student voices
The Acoustic Electronics Lab studies acoustic electronics, a fusion of acoustic engineering and electronics. A distinctive feature of the lab is that it deals not only with sound that people can hear, but also with inaudible ultrasound and nonlinear acoustic phenomena. Recently, it has been studying measurement and imaging techniques that use nonlinear ultrasound phenomena, techniques for improving sound environments, and the safety of ultrasound use. The lab approaches these topics through theory, computer simulation, experiments, and the design and prototyping of devices.

Kota Takahashi, Associate Professor

The Takahashi Lab studies the handling of sound signals through digital signal processing. The lab proposes a new kind of mixer, the "smart mixer," which has a mechanism for analyzing and processing input sound. It also works on remote choir technology, which automatically turns choir recordings made under varied conditions into a single finished piece. To process sound in real time, the lab also uses FPGAs, which are rewritable integrated circuits.

Yoshikazu Washizawa, Associate Professor
0 student voices
The Washizawa Lab studies machine learning, signal processing, pattern recognition, and biosignal processing. Statistical signal processing and optimization are also listed among its research keywords. Its registered research fields are intelligent informatics, foundations of informatics, and fundamental brain science.

Yoshiyasu Ueno, Professor
0 student voices
The Ueno Lab studies ultrafast information and communication technology that manipulates optical signals while keeping them as light. Using its own original approaches, the lab studies new optical materials, devices, and circuits, aiming to handle high-speed optical signals at 200 gigabits per second. Its research fields are ultrafast optoelectronics, quantum electronics, optical signal processing, and optical frequency combs. The lab also works on optical logic gates, which serve as an "optical transistor" to replace the electronic transistor.

Takashi Kato, Associate Professor
0 student voices
The Kato Lab was launched in October 2022 and studies new applications of optical frequency combs (optical combs) and ultra-precise optical measurement methods. An optical comb is broadband, phase-aligned light whose spectrum consists of lines evenly spaced on the frequency axis like the teeth of a comb. The lab works on developing optical phased arrays and methods for measuring 3D shapes instantaneously. It conducts joint research with the Minoshima Lab and the Asahara Lab in the same Department of Engineering Science.

Masato Sakano, Associate Professor
0 student voices
The Sakano Lab directly observes the electronic and spin states of materials in which quantum mechanical effects appear prominently, aiming to understand and open up new physical properties. Its targets are bulk and nanoscale materials, such as topological materials and artificially stacked two-dimensional crystals. In addition to receiving samples from collaborators in Japan and abroad, the lab also works on fabricating samples of stacked two-dimensional crystals itself. The lab carries out joint research using large shared-use facilities such as NanoTerasu and the Photon Factory at the High Energy Accelerator Research Organization (KEK).

Chiaki Ohae, Associate Professor
0 student voices
The Ohae Lab researches creating new laser light sources by freely manipulating nonlinear optical processes. Using a method that manipulates nonlinear optical processes by controlling the phase relationship of light, the lab aims to obtain single-frequency laser light at any wavelength from the mid-infrared to the vacuum ultraviolet. Using vacuum ultraviolet laser light, the lab is also working on laser cooling of hydrogen and antihydrogen atoms. The lab is also attempting to control electric current at ultrafast speed by controlling the waveform of light to the extreme.
