My research interests encompass the cardiovascular health effects of the natural and built environments and the role of geospatial factors and health disparities in these relationships. In particular, I am concerned with primordial prevention and the ways in which the natural and built environments can be shaped to positively influence health and health behavior. I have applied these research interests in studying built environment/physical activity and air pollution/cardiovascular disease relationships.
