Message

• My research interests lie in applied microeconomics, particularly health and labor economics. I use economic frameworks to understand individuals’ decision-making regarding their health investment and labor supply. My work also investigates how economic policies shape health and work outcomes, including drinking, work absences, and overall worker well-being. In addition, I study the role of time use in determining consumption behavior over the life cycle. Currently, my research focuses on how commuting time affects the allocation of time between husbands and wives and their well-being.
  The findings in my research contribute to policy discussions on minimum wage effects, policies related to commuting time, and strategies to reduce gender inequality within households. My goal is to further study household consumption, time use patterns, and gender inequality in Japan.
  
  I am responsible for teaching BSc first-year courses, in particular Math 1 Stat 1, and Introductory Mathematical Statistics.  Mathematical skills are essential for understanding economic models in both microeconomics and macroeconomics — for example, models of firms’ optimization decisions and the effects of fiscal and monetary policies. For students in economics and data science, the statistical concepts learned in my class form the foundation for advanced courses such as econometrics, advanced statistics, and machine learning.
