Research Interests
My research focuses on applying mathematical tools to analyze complex and chaotic phenomena, utilizing both theoretical and numerical methods. In particular, I’m working on UQ(Uncertainty Quantification) approaches to mathematical fluid dynamics.
I am also interested in interdisciplinary studies, where I would like to interact with many researchers in different fields by using mathematics.
specific themes
- Computing a stationary flow of 2D Euler equation with Hamiltonian Monte Carlo
- Mathematical analysis of data assimilation
- Creating the fundamental framework of data assimilation with topological data
keywords
Uncertainty Quantification(UQ), mathematical fluid dynamics, Topological Flow Data Analysis(TFDA), data assimilation, interdisciplinary studies, machine learning, weather forecasting, bio-logging
