Brown's research examines how and why racial/ethnic stratification and other axes of inequality combine to shape health and wealth across the life course. This research interest is expressed in three foci: 1) using multidimensional approaches to stratification to investigate the intersecting consequences of social factors on health and wealth, 2) examining whether inequality increases or decreases over the life course, and 3) determining the extent to which various structural and psychosocial mechanisms underlie within- and between-group differences in health.
