Now

This page shows what I’m doing now. Updated 10 May 2026 from my home in Yokohama.

Working as an engineer in DNV

It’s business as usual. If you’re interested in my professional work, please visit my LinkedIn profile.

Graduate study at the University of Tokyo

I’m pursuing graduate study (currently a Master’s, aiming for a PhD) in the University of Tokyo’s Department of Systems Innovation at the Marine Hydrodynamic Laboratory.

It has been a while, and my research is progressing fast! My research focuses on nonlinear wave forces and hydroelasticity of floating offshore wind turbines. I’m afraid that I might be late to the party (many emerging papers and even commercial products are tackling the exact issue I’m trying to study), but let’s see what unfolds.

The classes I’m currently taking:

  • Complex Fluid System Modeling: Fundamental concept and knowledge of mathematical modeling of complex fluid systems related to the design of transportation system, the prediction of ocean environment, etc.
  • Risers and Pipelines: Fundamental aspects of design, fabrication, installation and operation of slender structures employed in exploration (drilling risers) and production (risers & pipelines) for oil and gas reservoir in deepwaters.
  • Systems Innovation Project 6 (CD2): Another reading assignment. I’m reading “Sea Loads On Ships And Offshore Structures” by O. M. Faltinsen.
  • Robotics: Robot kinematics and dynamics, control methods, and their applications to humanoid and flying robots.

Reading list

I’m currently reading:

  • Prisoners of Geography by Tim Marshall
  • Tracks on the Ocean by Sara Caputo

Other stuffs - vibe coding

Lately, I’ve been trying to use Claude Code to vibe code. I’m more on the skeptic side of using AI to code, but I found that it is actually making me more productive. I can delegate the tedious or unimportant things (for me, that would be the webdev, for example) and just focus on the most important stuff, such as verifying the outputs of the code or the main algorithm (for me, that would be numerical analysis).

I just finished a fun project by vibe coding: Wave Calculator It is a static web app to generate, plot and export ocean wave energy spectra.
