Tiara C. Willie PhD, MA

Principal Investigator

Tiara C. Willie

As a social epidemiologist, Dr. Willie aims to understand the distribution, determinants, and health consequences of gender-based violence (e.g., intimate partner violence, reproductive coercion, child sexual abuse) in order to reduce the prevalence of violence and related comorbidities. Guided by the social ecological model, her research focuses on individual-, relationship-, community-, and societal-level determinants of gender-based violence and examines the health implications of gender-based violence in order to develop interventions to reduce violence and improve mental, sexual, and reproductive health.
