The impact of early life exposures on the developing human microbiota is a key theme of my research laboratory. Although it is well documented that HIV infection is associated with an increased risk of oral opportunistic infections and diseases, little is known about how the microbial profiles of HIV-infected or exposed individuals might impact oral health. A core component of my work as a Research Associate for the monitoring and evaluation component for the President’s Emergency Plan for Aids Relief (PEPFAR) program was supporting HIV/AIDS treatment, care, and prevention to sub-Saharan African nations. As a result of an increased access to antiretroviral treatment in developing nations, there is need to study the effect of HIV exposure on oral microbiota in a growing population of children/adolescents who are perinatally exposed yet uninfected by HIV. Our work has reported differences in bacterial community composition in HIV infected children as well as those born to HIV infected mothers (perinatally exposed) but uninfected. We have also participated in investigating the effect of maternal and infant antibiotic use, early feeding practices, delivery mode and other environmental exposures on the developing human microbiota. By investigating shifts in the microbiome, my team and I hope to understand how microbiota modulation might present as an important therapeutic target for better long-term health outcomes particularly in young children. Building on my work on the microbiome, HIV and clinical expertise, I am currently focused on conducting large-scale human microbiome research in the context of longitudinal molecular epidemiology studies in young children. In addition, I am motivated by questions related to disease causality and the rigorous epidemiologic methods used to address them. Most recently, we have been involved in research related to SARS-CoV-2 epidemiology.
