Research

Summary

My research focuses on developing efficient numerical methods for hydrodynamic problems and their applications in the maritime industry. My research interests include sloshing analysis of LNG tanks, nonlinear seakeeping and wave loads analysis, and ship resistance & propulsion optimization. I am currently working on research projects in collaboration with shipyards and classification societies.
