AboutAbout the lab
Reading the motion of complex waves through mathematics
The Maruno Lab focuses on nonlinear waves and applied integrable systems.
The lab uses mathematics to theoretically analyze complex natural phenomena such as water waves.
It also develops numerical computation and simulation techniques for solving nonlinear mathematical models.
The lab also hosts lectures and seminars with researchers invited from abroad.
