Tiara C. Willie is a NIMH predoctoral fellow in the Interdisciplinary HIV Prevention Training Program at the Center for Interdisciplinary Research on AIDS. She earned her B.S. in Biology at the University of North Carolina at Chapel Hill and her M.A. in Women’s Studies at Southern Connecticut State University and. Her master’s thesis, My Existence is My Activism: Evaluating the Self-Manifestation of Strength amongst Women Experiencing Intimate Partner Violence, used empowerment theory to examine women’s perceived strength and locus of control among community women experiencing intimate partner violence. Her research focuses on building knowledge on gender-based violence (GBV) and HIV/AIDS from an intersectionality framework. Her nascent program of research explores the implications of individual, relationship, community, and structural- level determinants of GBV on the sexual and reproductive health of marginalized women, domestically and globally. This empirically informed research would be used to construct GBV and HIV prevention interventions. Her mentors are Dr. Trace Kershaw and Dr. Jhumka Gupta.
