My research is concerned with methods of data analysis for both quantitative and qualitative data. Using these methods, I have been researching following theme: relationship between social structure and mental health, continuity and change of marital relationship, structure and changes of one's life course, and so on. Recently I have been concerned with intergenerational reproduction of poverty and its effect on one's life course, as well as the effects of social welfare policy on them.

Human Sciences
Social Psychology

I study decision-making in social contexts, with a particular interest in the relationship between the establishment of social norms and human decision-making. My research to date has primarily used laboratory experiments to investigate how people prefer to distribute limited resources among members of society. More recently, I have been focusing on social psychology research that takes advantage of the increasing availability of real-world data and computational resources.

I am a medical anthropologist with interests encompassing the anthropology of science, biomedicine and psychiatry; depression and suicide; aging and dementia; and global health and preventive medicine. My book Depression in Japan (Princeton Univ. Press, 2012) examines the rise of depression and the emergence of psychiatry as a force of social transformation in Japan. My current project on dementia investigates the changing landscape of aging in the genomic age and the global psychiatrization of the life cycle.

I have conducted anthropological research on conflict and peace issues. My main research questions are: Why do people take part in the war, what type of experiences do people have in the battlefield, and how do people build and maintain peace in conflict-ridden areas? Currently, I am also researching how large-scale development projects have influenced the livelihood of local people in Africa.
