Associate Professor, Department of Population Health
I am an Associate Professor in the Department of Population Health at New York University. I completed my PhD in infectious disease epidemiology at the University of North Carolina at Chapel Hill and a post-doctoral program in drug dependence at the National Development and Research Institutes, Inc. I completed a longitudinal cohort study among African American men being released from prison incarceration to examine factors driving STI/HIV-related drug use and sexual risk after release and buffering effects of social support from primary committed partners. Informed by cohort study findings, members of my team currently are piloting a novel couples-based STI/HIV prevention intervention adapted for jail/prison that aims to maintain and strengthen ties during incarceration to ensure intact support networks upon community re-entry, a stressful period when STI/HIV-related substance use and sexual risk is heightened. In a second line of work, I have extensive experience conducting secondary data analysis research using large nationally-representative data sources, including the National Longitudinal Study of Adolescent to Adult Health (Add Health). I completed an Add Health study that evaluated the role of adolescent substance use in adolescent and adulthood STI/HIV risk including the degree to which substance use-related criminal justice involvement mediates the association between substance use and STI/HIV risk. I have been funded to extend this Add Health work to look earlier in the life course at an upstream factor—childhood trauma—that may drive adolescent and adulthood substance use, criminal justice involvement, and infection.
Our team has conducted numerous studies on HIV-related drug and sex risk after release from incarceration including studies to establish incarceration as a structural determinant of HIV transmission. Specifically, our team has developed a novel conceptual model hypothesizing that incarceration, by disrupting social and sexual networks, contributes to reduced social cohesion, elevations in mental disorders, and drug and sex risk behaviors that drive HIV infection.

Contribution to Science
2. Studies to highlight the link between untreated mental disorders and sexually transmissible infection risk in vulnerable populations including jail and prison inmates. We have examined the link between mood and personality factors and STI/HIV risk and have highlighted the importance of treating mental disorders as a component of addressing the race disparity in STI/HIV. In addition, we have documented the importance of both mood and personality disorders as strong independent correlates of STI/HIV risk among incarcerated black men, underscoring the need for prisons and jails to screen for and provide treatment of common treatable mental disorders to improve the health and well-being of inmates.
3. Network factors in HIV transmission. Using sociometric and egocentric network data, we have evaluated network-related factors associated with drug use, sex risk, and infection risk. These studies highlight the importance of social environment and peer influences in HIV risk.
4. Health disparities research focused on race and gender differences in infectious disease. We have demonstrated race and gender differences in levels of drug use, depression, and criminal justice involvement and in associations between these factors and sexual risk determinants of STI/HIV among adolescents and young adults at the national level. Findings have highlighted the need for group-specific approaches to development of interventions to prevent and address drug use, mental disorders, and HIV infection.
Ongoing Research SupportR01 DA044037 - Khan (PI) - 07/01/2017 – 04/30/2022 Stop-and-Frisk, Arrest, and Incarceration and STI/HIV Risk in Minority MSM This study aims to examine multiple levels of criminal justice involvement in the STI/HIV risk of minority men who have sex with men (MSM) by using epidemiologic and computer simulation. The study will inform development of structural STI/HIV prevention approaches in correctional settings. Role: PI U01 AA020799 - Braithwaite (PI) - 09/06/2011 – 08/31/2021 Consortium to Improve Outcomes in HIV/AIDS, Alcohol, Aging & Multi-substance use (COMpAAAS) Our proposal creates an interactive, web-based simulation model of HIV transmission that can help decision makers prioritize which intervention designs are most effect by tailoring results to patients and feasibility constraints. Role: Co-Investigator R01 AA024706-01A1 - Braithwaite (PI) - 09/15/2016 – 06/30/2021 Should screening and treatment strategies for unhealthy alcohol misuse in HIV infected persons vary with smoking, depression, and substance abuse? This proposal aims to inform guideline development for screening and treatment of unhealthy alcohol use, substance use, smoking and depression in HIV-infected persons. The target population is HIV-infected individuals in care at integrated health systems in regions with high HIV incidence.
