Associate Professor / Kohei WATABE
He is very friendly and trusts students, so he allows us to advance research at our own pace. Students are encouraged to learn skills and knowledge that can be used even after graduation, and they can also come for consultation.

Research Content

The Internet that supports our lives is said to be one of the largest systems in human history. That is why it is a challenging issue to control this huge system without interruption. For example, in telesurgery, using a robot arm or autonomous driving via networks, network failure can cause a life-threatening problem. Our laboratory aims to create a communication infrastructure that never stops even on a large scale and recovers quickly if halted.

A Day in the Lab

At ComNets Lab., except for a meeting to report progress of research for members, there are almost no fixed schedules. Individual meetings can be freely scheduled without appointments. Therefore, part-time jobs and job hunting can be compatible with research activity. Since Dr. Watabe likes alcohol and cooking, there are many events such as fireworks, cherry blossom viewing, and takoyaki parties. Because of that, students can enjoy both research and private life in the laboratory. In addition, Dr. Watabe recommends challenges other than research to students. Meetings where students show self-made IoT systems or web applications are held.

Newcomers develop Pac-Man in boot camp.
