Dr. Croker's research aims at a deeper understanding of how minoritized identity (i.e., race, ethnicity, age, HIV status, LGBQ identity) influences health behaviors in order to inform policies that promote health among vulnerable groups across the lifespan. Presently, Dr. Croker's research examines the relationship between minoritized identity and polysubstance use (i.e., tobacco, cannabis, and alcohol products), particularly among adolescents and emerging adults (AEA), & older adults with HIV.
