The primary goal of Dr. Hornbuckle’s research is to make a positive impact on health disparities in underserved groups through the promotion of physical activity and exercise. The majority of her current work is centered in African-American communities, and aims to reduce cardiometabolic risk through the development and implementation of culturally relevant physical activity and exercise interventions.
