Smart Mobility & Transportation

We research data-driven technologies, including transportation and urban digital twins, that optimize the movement of people and goods in a safe, comfortable, and efficient manner.

Disaster Management & Resilience

Working toward building resilient societies, we develop information and communication technologies for disaster prevention and mitigation, as well as efficient situational awareness, aiming to achieve socially equitable disaster preparedness that leaves no one behind.

Smart Agriculture & Primary Industry

We research smart agriculture technologies that introduce digital twins, IoT, and AI to farming and primary industries, enabling field environment visualization, crop growth prediction, and operational efficiency.

Space & Satellite Technologies

We are developing control algorithms for distributed satellite systems where multiple small satellites operate cooperatively, along with efficient inter-satellite communication protocols and flight formation technologies.

Intelligent Environment & Wireless Sensing

We aim to create intelligent environments where physical spaces themselves possess "intelligence" and can sense and respond to human needs and behaviors. Our research and development includes wireless/radio-based human sensing and privacy-conscious three-dimensional remote space sharing systems.
