AboutAbout the lab
Clarifying the link between eating habits and health through data
The Social and Preventive Epidemiology Lab focuses on nutritional epidemiology.
Nutritional epidemiology is a field that uses epidemiological methods to clarify the relationship between what and how people eat and their health.
The lab studies how to assess diet itself, and uses those methods to investigate the relationships between dietary habits and a range of health problems.
The lab was established when the Department of Public Health (School of Public Health) was founded, and Prof. Murakami was appointed Professor in August 2023.
