Professor / TSUBONE Tadashi
Tsubone sensei is a kind and reliable teacher. He is passionaete about research and values communication with students.
If you have any problems, he is easy to talk to and cares about you outside of research activities.

Research Content

The world is full of complex phenomena such as schools of fish and cloud movement. Nonlinear dynamics is hidden in them.
Our laboratory focuses on nonlinearity to reveal and realize behaviors and characteristics that cannot be explained by linear systems, and apply it to engineering. We have expertise in causing and analyzing nonlinear phenomena on circuits.
Recently, we have researched: Bifurcation analysis of dynamical systems, Levitation of objects by ultrasonics, Synchronization by walking on a bridge, Cellular automaton method, System identification, Machine learning predictions using nonlinear dynamics.

A Day in the Lab

Each student has one research theme. Our goal is to present our research at conferences and publish it in academic journals. There is a monthly workshop and a seminar twice a week, so you can easily consult with teacher and laboratory members. In addition, We are actively presenting our research at national and international conferences, and you can grow through valuable experiences.
In our laboratory, we are good teammates and often go out to eat or have fun together. There are many activities such as travel, BBQ, football, and skiing, so you can have a memorable student life.
