Current Projects

Established in 1993 and previously led by Dr. Beryl Koblin, the Laboratory of Infectious Disease Prevention is a leader in HIV and infectious disease epidemiology and prevention research. We are part of the largest clinical trials program devoted to the development and testing of preventive HIV vaccines worldwide (www.hvtn.org). As part of the global response to COVID-19 caused by SARS-CoV-2 virus, we are also part of the clinical trials program devoted to the development and testing of SARS-CoV-2 vaccines and monoclonal antibodies to prevent COVID-19. We use epidemiology to stay up to date on who is at risk for HIV and other infectious diseases and why. We design and test innovative prevention strategies to increase HIV testing and pre-exposure prophylaxis (PrEP) uptake and reduce risk. We conduct our epidemiology and clinical studies and community engagement through our research site, Project ACHIEVE (www.projectachieve.org).

Our research collaborators include Columbia University, Harlem Prevention Center, and Bronx Prevention Center. Together, we form the NIH-funded Columbia Partnership for Prevention and Control of HIV/AIDS Clinical Trials Unit.

SARS-CoV-2 Vaccine and Monoclonal Antibody Studies

In collaboration with the NIH/NIAID-funded COVID-19 Prevention Trials Network (CoVPN) and with the Columbia Partnership for Prevention and Control of HIV/AIDS Clinical Trials Unit, our research involves implementation of multiple Phase 1-3 SARS-CoV-2 clinical research trials to test the safety, tolerability, and efficacy of vaccine products and monoclonal antibodies to prevent COVID-19.

HIV Vaccine and Monoclonal Antibody Studies

In collaboration with the NIH/NIAID-funded HIV Vaccine Trials Network (HVTN) and with the Columbia Partnership for Prevention and Control of HIV/AIDS Clinical Trials Unit, our research involves implementation of multiple Phase 1-3 clinical research trials to test the safety, tolerability, and efficacy of HIV vaccine products and monoclonal antibodies to prevent HIV infection.

HIV Injectable Pre-Exposure Prophylaxis Study

In collaboration with the NIH/NIAID-funded HIV Prevention Trials Network (HPTN), this multi-site, multi-country HPTN 083 study is a Phase 2b/3 study comparing injectable cabotegravir to emtricitabine/tenofovir (FTC/TDF) for preventing HIV infection in men who have sex with men and transgender women.

Neighborhoods, Networks, and the HIV Care Continuum

This NIH/NIMH-funded three-phase research study involves a mixed methods approach to ascertain unique, salient neighborhood and network factors that influence HIV care continuum outcomes (retention in care, ART adherence, and viral suppression) among HIV-infected men who have sex with men in New York City using qualitative interviews and spatial analysis and multilevel modeling. This is followed by a longitudinal study among 500 HIV-infected MSM over two years to evaluate the influence of neighborhoods and networks on HIV care continuum over time.

Pre-Exposure Prophylaxis in Women

This NIH/NIMH-funded R34-funded three-phase project seeks to develop and pilot an intervention to enhance uptake of pre-exposure prophylaxis (PrEP) among women at risk for HIV, and support adherence, and linkage to care in New York City and Philadelphia. Text based messaging will be used to encourage PrEP adherence, and the feasibility and acceptability of the intervention will be tested.

Hepatitis C Infections among Men Who Have Sex with Men

This Merck Investigator Sponsored Program (MISP)-funded research aims to determine the prevalence of recent and chronic hepatitis C (HCV) infections among MSM in NYC, map HCV infections by home, social, and sexual neighborhoods, and determine clusters of genetically linked HCV variants among recently and chronically HCV-infected MSM in NYC using phylogenetic analysis.

Barriers and Facilitators to Blood Donation

This pilot study seeks to identify and describe motivations, barriers, and facilitators to blood donation among Black donors by analyzing YouTube video content and qualitative data analysis.
