Ph.D. Student in Engineering
Kumamoto University, Japan
I am a third-year Ph.D. student in Engineering at Kumamoto University and a research fellow of the Japan Science and Technology Agency SPRING Program. My research examines the reliability of household travel surveys, with a particular focus on identifying and correcting trip underreporting through response-diligence indicators and behavioral models. I also study travel behavior among older adults, license surrenders and mobility, and the influence of the built environment on travel demand. My broader interests connect discrete choice and latent class models with complex network analysis, spatial analysis, and machine learning to understand mobility patterns and support evidence-based transportation policy.
