Hayami Koga holds a PhD in population health sciences from the Department of Social and Behavioral Sciences at the Harvard T.H. Chan School of Public Health. She also holds an MD from the University of Occupational and Environmental Health in Japan. Koga’s doctoral work explored whether psychological well-being, at a population level, is an important asset that contributes to a longer and healthier functioning lifespan. She sought new approaches to improving population health while reducing inequities. Based on findings from her research, the workplace appears to be a promising setting in which to implement population-level interventions. As a Bell Fellow, Koga plans to further develop this approach by working with a hospitality group based in Japan that operates hotels and other venues around the globe.
