Embedded System

An embedded system is a modular micro-computer with a dedicated function. It can assess on-site condition and proide timely disaster prevention and mitigation without human interference.

Numerical Modeling

Numerical modeling has been a useful tool for practical applications and analysis such as the development of early warning system and human behavior preciction.

Cyper-Physical System

Physical and software components are deeply intertwined in cyber-physical systems, each operating on different spatial and temporal scales, and interacting with each other that change with context.

History about the lab.

  • 2018 August

    Our Humble Beginnings

    Josh started his new job in National Chiao Tung University. Hao-Ming, Chia-Wei, and Szu-Hao were the first three members of the team.

  • March 2019

    THINKLAB is officially born

    The lab name "THINKLAB" has officially confirmed. The core values of the lab are echnology . Hydrology . Integration . Need . Knowledge. Major focus is disater prevention and mitigation. Obaja from Indonesia and Hong-Ming joined the lab as the first phd student and a post-doctoral researcher at the same time. Kevin and Allen started their independent stuies with the lab during the same time.

  • July 2019

    Phase Two Expansion

    The lab started its first edge-computing device and associated experiment. Welocme two graduate students, Tina and Allen, joined the lab.
