The lab and members

This department was established in 2000 with Masahiro Kihara as its first professor. The Department of Socio-epidemiology, which integrates epidemiology and social science, has advocated a comprehensive methodology for public health, and has promoted education and research that inherits the tradition of Kyoto University’s emphasis on this field. In addition to pioneering and leading epidemiological research on HIV infection in Japan, the University has actively promoted global health research with the participation of many students from developing countries, and in 2006 was designated as a Joint Research Center of the Joint United Nations Programme on HIV/AIDS.

In September 2020, Naoki Kondo was appointed as the second professor. Inheriting the tradition of field-oriented research, Professor Kondo emphasizes the importance of using large-scale quantitative data and of implementing the findings from research in a wide range of social systems, while collaborating with diverse organizations. The current lab name is the Department of Social Epidemiology.



Naoki Kondo

Research: Social epidemiology, Health equity, Social determinants of health

People’s health is affected by social circumstances such as education, income, occupation, and their connections. It is also affected by national and regional policies, culture, economic trends, income disparity, and other social factors. Therefore, it is not possible to protect people’s health only with approaches that encourage individuals to take rational actions such as “exercise moderately” or “stop smoking”. Social epidemiology uses epidemiological methods to elucidate these “social determinants of health” and to control the health disparities that arise from them. Our goal is to create a society in which everyone can be naturally healthy.

Assistant Professor

Yukiko Honda

Research: Social epidemiology and Socio-epidemiology, Maternal and child health, Mental health, Global health

Dr. Honda is intrigued by the question of what can serve as a lasting support throughout our journey in life. The answer to this question may not be singular. Using epidemiological research methods, she is dedicated to exploring these diverse answers both quantitatively and qualitatively. Her ultimate objective is to contribute to the prevention of undesired isolation among children and parents. Additionally, she aims to contribute to the establishment of support systems that consider the entire life course.

Research Fellow

Hiroshi Habu

This integration aims to contribute to the creation of communities  that foster individual well-being. Furthermore, he’d like to deepen his understanding of facilitation techniques that can effectively bridge these two aspects within the community.
