Spatial Inequality
The CGA’s work on spatial inequality has explored the ways geographic difference in access, exposure, and opportunity, shape social, financial, and health outcomes. Our work has analyzed disparities in telehealth and clinic access, neighborhood conditions linked to asthma, transit-based accessibility to hospitals, and various digital divides. Methodological contributions include accessibility modeling and reproducible geospatial workflows that support equity-focused research in urban and regional contexts.
