Ph.D. Student in Engineering

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 main research interests are travel behavior analysis and bias correction in travel surveys. Moreover, as Levinson (2026) notes, randomised controlled trials are often difficult in transportation research, making causal identification challenging. Therefore, my research also explores quasi-experimental approaches to provide causal evidence on travel behavior and transportation policy, rather than focusing solely on associations. Lastly, some related research interests also include complex network analysis and the study of urban functions. The primary goal of these studies is to provide high-quality data for understanding human mobility and to generate reliable empirical evidence for transportation policy.
