HIV Dynamics

We work closely with the Rakai Health Sciences Program and other collaborators to study HIV transmission in sub-Saharan Africa

We work on a variety of epidemiological studies focused on HIV transmission dynamics and the impact of prevention interventions. Our research largely takes place in Sub-Saharan Africa but we have also collaborated on domestic initatives.

We closely collaborate with the Rakai Health Sciences Program (RHSP) in Uganda, which is one of the leading HIV research institutions in Sub-Saharan Africa. Rakai, located in Southwest Uganda, is where the first AIDS cases were identified in Eastern Africa and today it remains one of the highest-burden districts in the region with an overall HIV prevalence of ~14%. However, within Rakai there is substantial geographic heterogeneity in HIV prevalence ranging from 9-43% at the community-level. We currently support NIH and BMGF initiatives to understand the role of extremely-high-prevalence communities (i.e. "geographic hotspots") and other key populations within the broader regional epidemic with the overarching goal of informing targeting HIV prevention initiatives under PEPFAR Phase III. Our work with RHSP includes dynamic HIV modelling and viral phylogenetics conducted in collaboration with the PANGEA-HIV consortium and researchers (and friends!) at Oxford University and Imperial College London in the UK.

We also have an iniative supported by the Johns Hopkins Center for AIDS Research/NIH to use network models and viral phylogenetics to inform real-time interventions to prevent HIV among young men who have sex with men in Baltimore City, Maryland.
