Research to Improve Health

Cutting-edge research on the social and structural drivers of health.

To understand the drivers of population health, the systems around populations must be understood — as it is not individuals themselves, but the social and structural inequities individuals encounter in their everyday lives that shape their health.

This is a major paradigm shift from focusing on a single specific pathway toward considering how the entire system fits together to produce health inequities for a particular population. This work requires a shift toward complex modeling and computational approaches. It also requires new tools and methods for the capture, integration and analysis of rich social data necessary to understand systemic influences on individual health.

Through numerous studies, our team has been at the forefront of understanding of the social and structural drivers of population health via measurement tools, modeling and analysis, and the transdisciplinary integration of scientists and community members. Some of our current projects include:
