Health Promotion and Human Behavior (Professional Degree Course / Latter Doctral Course)
Kosuke Inoue, MD, PhD
In this department, we generate evidence to advance health promotion by applying analytical methods such as causal inference and machine learning to randomized controlled trials and observational data, while also incorporating perspectives from behavioral science.
Regardless of your specialty or background, if you are interested in exploring questions such as “Why does a particular intervention or policy improve health?” and “For whom is it most effective?”, please feel free to reach out to us.
Research and Education
We integrate causal inference and machine learning to advance next-generation personalized strategies for prevention and health promotion. Beyond the traditional “high-risk approach,” we propose a “high-benefit approach” that leverages treatment effect heterogeneity to improve resource allocation and reduce health disparities. Our research extends from lifestyle-related and other chronic diseases to broader social and environmental determinants, with the goal of establishing a new framework for personalized public health. We also pursue practical research that bridges clinical medicine, public health, and social implementation, including optimizing interventions informed by health behavior theory and behavioral economics, supporting behavior change through smartphone applications, and evaluating intervention effectiveness via international collaborations.
In education, we focus on cultivating expertise that connects epidemiology, clinical medicine, and basic sciences. Graduate students are guided from research design to publication in leading journals, with several theses published internationally. Through active collaboration and researcher exchange with institutions such as UCLA, Harvard, and Yale, we foster the next generation of leaders in public health and epidemiology in Japan and worldwide.
