In her PhD research Dr. Colleen Reid examined how poverty and exclusion influence the health of marginalized women. Her interdisciplinary PhD bridged social epidemiology, health promotion, feminist theory, and participatory action research. Colleen developed a theory of cultural, institutional, and material exclusion and engaged in a feminist action research project to better understand the relationship between poverty and women’s health. As a postdoctoral fellow, Dr. Reid is now developing and testing conceptualizations and measures of health inequalities with a specific focus on Canadian women. The research involves conducting an extensive literature review, integrating qualitative and quantitative measures, and working collaboratively with health researchers to move theories and methodologies toward practical and policy applications. This research will address major gaps in health inequalities research, a critical step for enabling health researchers to address root causes of social inequalities.
