Her research explores social determinants of substance use and sexual risk behavior among U.S. adolescents and young adults, and the ways in which laws and policies may serve as structural drivers of HIV transmission.

Kirschstein Predoctoral Individual National Research Service Award (F31) from the National Institute of Mental Health to examine the influence of state-level laws related to confidentiality in sexual health services on U.S. adolescents’ HIV testing practices.
