I have developed expertise in both women’s health and HIV, and these interests have merged into a program of research that addresses psychosocial aspects of HIV care and prevention, particularly among women and underserved populations, in both domestic and international settings. Much of my work occurs in the province of KwaZulu-Natal, South Africa, an HIV hyperendemic setting that has the highest concentration of pregnant women living with HIV in the world. I am currently leading a large prospective cohort study (NIMH 112385) that aims to identify factors that influence postpartum attrition from HIV care among women in KZN—an important and understudied link in the HIV cascade that is critical to public health goals to end the epidemic.

Recent work has focused on developing interventions to support adherence to pre-exposure prophylaxis (PrEP) for prevention of HIV. I led the design of an adherence intervention for serodiscordant couples participating in the Partners PrEP trial in Uganda; ours is the first published adherence intervention for individuals using PrEP. I also led the design and execution of PrEP adherence interventions in collaboration with colleagues at the Fenway Institute/Fenway Health and currently serve as Co-PI (with Kenneth Mayer, MD) of an Adolescent Trials Network (ATN) funded-study (NICHD 089881) in which we are adapting a PrEP adherence intervention to meet the needs of young men who have sex with men. Lastly, I am a member of the protocol team for HIV Prevention Trials Network (HPTN) study 083. As part of this work, I developed an ancillary proposal to collect qualitative data from participants on this study to better inform our understanding of how to deliver and implement injectable PrEP.
