Healthcare Access, Utilization, Sociodemographic & Spatial Factors

Where you live matters.


The HAUSS lab focuses on cancer health disparities through the lens of the social determinants of health (SDOH) using a socio-ecological perspective, with particular foci on healthcare access and utilization and the intersection of race/ethnicity, rurality, and other identities. The lab incorporates GIS and spatial analysis to examine spatial patterns of disease as well as geographical medical accessibility (distance and travel time analyses).

Current projects include survey-based research assessing delayed medical care, cancer screening uptake, and availability of social supports through primary care settings. The lab also conducts research using secondary data sources including provider databases and electronic health records.
