Ocean is turbulent. However it shows some order, such as currents. How can we understand this system? With this question in mind, I look at data collected by floats, ships, and satellites.

I am interested in quantifying ocean turbulence. I am also interested in the role played by turbulence in forming the ocean general circulation. In particular, I study how strength and efficiency of oceanic turbulence that cannot be simulated in numerical models can be estimated from observed parameters, depending on mechanisms of the turbulence. I approach the problem both theoretically and observationally. For detail, please have a look at 伊地知 (2024)

I am interested in elucidating the universal properties of complex nonlinear and non-equilibrium fluid phenomena. My current aim is to develop a robust description of the processes governing diffusion phenomena in the ocean, using tools such as dynamical systems theory and topological geometry.
