As the Director of IHV Division of Epidemiology and Prevention and Global Director for the Center of International Health, Education, and Biosecurity (CIHEB), Dr. Charurat has over 15 years of research experience in among vulnerable and key populations, HIV treatment and prevention service delivery, and HIV surveillance. In the mid-1990’s, Dr. Charurat was an active investigator in the NIH-funded Women and Infants Transmission Study (WITS) when mother-to-child HIV transmission was fairly high in the U.S., and in the early 2000’s he pioneered the mobile recruitment platform that successfully provided PEPFAR services to key populations such as female sex workers, men who have sex with men, and higher-risk pregnant women (CDC 200-2003-01716.)  Dr. Charurat published a first molecular characterization of circulating HIV-1 infections in Nigeria and is working with the CDC and the GON to improve incidence rate determination and surveillance across different populations in Nigeria. He is current PI on three R01s: R01DE025174 characterizes microbiome among HIV-Exposed but uninfected infants in Nigeria; R01AI120913 targets marginalized MSM and determine intervention for treatment as prevention (TasP) and pre-exposure prophylaxis ARV (PrEP);  and 1R01HD089866, an HIV adolescent transition to adult care study.  Additionally, he just completed R01MH099001 studying barriers to engaging MSM in services in Nigeria.   Dr. Charurat recently led the implementation of the Nigeria HIV/AIDS Indicator Survey (NAIIS) using the population-based HIV impact assessment (PHIA) standard (U2GGH002108).  He is also the PI of a 5-year award from PEPFAR through the CDC to conduct PHIA surveys worldwide (U2GGH002172).

Research Interests

Dr. Charurat’s research career began with studies of mother-to-child transmission of HIV, publishing on the ability of highly effective antiretroviral treatment of the mother to eliminate pediatric transmission and later documented the adverse consequences of “mixed” feeding of African infant.  Recently, through NIH R-01 funding, he began investigating HIV exposed uninfected infants and the role of the gut microbiome in developmental delays.  His studies involving most at risk populations are at the cutting edge of current global strategies.  His work in this arena documented the dynamics of acute HIV infection and laid the foundation for subsequent studies that mapped transmission hotspots which in turn led to successful NIH R-01 grant funding (TRUST Project) that employ sophisticated recruitment strategies to engage Men having Sex with Men in treatment and prevention services and documenting the impact of treatment as prevention.  Most recently, expanding upon the TRUST study, a new NIH RO1 grant (Building TRUST) integrates phylodynamic modeling to pattern incidence and prevalence over time.

Grants and Contracts

1R01DE025174-01, PI, 09/23/2014-07/31/2019, Microbiome and Health Outcomes among HIV-exposed Uninfected Infants  (MARGIN) - This study is investigating the acquisition of a distorted gastrointestinal (GI) microbiome resulting from exposure to maternal HIV infection in HIV-exposed but infected infants in Nigeria is associated with post- natal growth as measured by increased nutritional deficiencies, increased GI permeability, and adverse clinical outcomes.


1R01AI120913, NIH, PI, 07/01/2015-06/30/2020, Building TRUST - The WHO calls on the need to re-energize and strengthen HIV programs so that all high-risk “key populations” benefit from the on-going advances in HIV antiretroviral-based prevention methods.  Building TRUST studies a group of men who have sex with men in Nigeria to understand the barriers to effective treatment and prevention uptake in order to better prevent new infections and save lives of those infected.


1R01HD089866, NIH, MPI, 07/01/2016-06/30/2021, Adolescent to Adult Patient-centered HIV Transition (ADAPT) - The ADAPT study is a randomized trial of innovative interventions targeting gaps in care that are major drivers of loss in the ART continuum of care cascade among adolescents and increasing missed opportunities to engage adolescents into care.  The specific aims of ADAPT are: (a) to inform strategies for transition services in resource-limited settings; (b) to examine the developmental, clinical, and other factors that predict a successful transition; and (c) to gain fundamental insight on implementation barriers among African adolescents through the application of the ego-network defined social support that will inform targets for structured intervention.

In Nigeria, UMB led by the School of Medicine, is a leading public health partner with the Government of Nigeria, several donors and local institutions.
