    Collapse Overview
    Anna Leddy is postdoctoral fellow in the Traineeships in AIDS Prevention Studies (TAPS) at the University of California, San Francisco. Her research seeks to understand and intervene upon social and structural factors that contribute to HIV and limit engagement along the HIV care continuum. Most of this work is conducted in sub-Saharan Africa and involves vulnerable populations including women, adolescents, and female sex workers. Recently, she has worked on a community mobilization intervention with female sex workers in Tanzania to prevent GBV and improve HIV prevention and engagement in HIV care and treatment. Her research is informed by social and behavioral theory and employs both qualitative and quantitative methods to gain a more nuanced understanding of the dynamics that increase risk for HIV and limit engagement in HIV care and treatment.
