Extensive Research Description
My clinical, educational and research interests revolve around improving the care and health outcomes of individuals living with or at risk for HIV/AIDS in domestic and international settings. Since 2011, I have been a member of the Yale AIDS Clinical Trials Program, and Director of the Program (since May 2017) and have been a principal and or co-investigator on numerous pharmacokinetic, phase 2 and 3 safety and efficacy trials of novel antiviral compounds (HIV). Most recently, given the alarming rate of new infections among men who have sex with men (MSM), I have added HIV prevention trials to my clinical trials activities. I am currently a co-principal investigator on a Yale CIRA funded project, which has supported the formation of a cohort of men who have sex with men, who are at high risk for HIV and are engaged in HIV PrEP services in order to study the impact of substance use on retention in care and adherence to PrEP.
Internationally, as a visiting professor to the National University of Rwanda since 2012, I have and continue to mentor medical residents and junior faculty, conducting meaningful clinical research projects that are locally relevant and addressing important infectious diseases-related problems (particularly HIV/AIDS and antimicrobial resistance). Similarly, in Liberia, as the Program Director of Yale’s Office of Global Health’s efforts to support Internal Medicine residency training, we have received funding (World Bank and HRSA) to support strengthening clinical research capacity in Liberia.
