Current position

April 2026 - Present  Project Researcher (JSPS Research Fellowship for Young Scientists PD), The University of Osaka. Host: Haruya MIZUTANI

Research Interests

Linear and nonlinear dispersive equations

• Linear estimates (e.g., Strichartz estimates)

• Long-time behavior of solutions (e.g., Scattering, modified scattering)

• Well-posedness theory, including probabilistic methods

Connections between two or more PDEs

• Semi-classical limit from the Hartree equation to the Vlasov equation

• Derivation of the kinetic/fluid equations

Related to the above topics, I am also interested in

• Kinetic and fluid equations themselves

• Harmonic analysis, operator theory, and probability theory as powerful toolboxes
