After earning his Ph.D. in science, he joined the Communications Research Laboratory (now NICT) in 1995. There, he has conducted research on crustal deformation monitoring using VLBI and GPS, spacecraft tracking using VLBI, technologies for a compact VLBI system, GNSS time and frequency transfer, and geodetic measurements for evaluating 10^-18-order frequency uncertainties of optical atomic clocks. Ph.D.(Science).

In March 2017, he completed the doctoral program at the University of Tokyo Graduate School and obtained a PhD in Engineering. After working as an assistant professor at the Center for Northeast Asian Studies at Tohoku University, he joined the National Institute of Information and Communications Technology (NICT) in April 2021. He is currently engaged in research and development of image analysis technology and video IoT at the Resilient ICT Research Center at the NICT Network Research Institute. In 2020, he received the IEICE Paper Award.

To realize fully autonomous driving, the acquisition of the car's environment, the recognition of traffic signs and obstacles, the decision of driving action, and the control of the car should be repeated rapidly. The in-vehicle network is used to transmit large amounts of data with low latency in this loop, which must also meet stringent environmental, electromagnetic compatibility, and reliability requirements. To solve this problem, a novel in-vehicle optical network system (SiPhON: Silicon Photonics based in-vehicle Optical Network) has been proposed and successfully demonstrated.
