Research Interest

The Evolution of new communication technologies will change our communication style drastically. In that sense, the Internet made a big change in our life. It connects most of the computers on the Earth with each other and we achieved the biggest computer network we didn't have ever before.

We are now in the phase to change the way how we operate and use computers. The computers are not just calculators inter-connected with each other, but they are a kind of a virtual computer serving various applications utilizing many inter-connected computers as components for the services. The Internet is changing its role from an interconnection technology to a core component of Internet-scale computing. The Internet is a computer now.

We have been extending our ability using new technologies. The Internet expanded our reachability in communication. Cloud and IoT technologies expanded our sensing and actuating abilities to reach remote eyes and hands. The Internet-scale computer will expand how we think and how we act, which means it extends our intelligence.

We are working on researching to build an Internet-scale computing environment to realize the Internet of Intelligence.
