    Typhanye V. Dyer, PhD


    Dr. Typhanye Dyer is an epidemiologist and health disparities scholar whose research examines the influence of social, psychological, and behavioral factors on STI and HIV-risk in Black populations. She has over 15 years of experience conducting research exploring HIV infection and health-related outcomes among Black underserved populations, including sexual minorities and women. The majority of her work involves examining syndemics (intersecting psychosocial and structural barriers to care) among sexual minority Black men, including the impact of trauma, poor mental health and criminal justice involvement and STI/HIV for Black gay and bisexual men.

    Rodman Tupin, PhD


    Dr. Rodman Turpin is a Research Assistant Professor in the Department of Epidemiology and Biostatistics at the University of Maryland, College Park and current Domestic Scholar with the HIV Prevention Trials Network (HPTN). He is a biostatistician and epidemiologist with a research focus on mental health and HIV/STI-related outcomes affecting sexual and racial minority populations, particularly Black sexual minority men. His research incorporates the use of unique measurement and analytic approaches (latent class, profile, and transition analyses, structural equation modeling), particularly in assessing syndemics of synergistic psychosocial and structural factors negatively impacting health. Much of his work examines interactions between healthcare access/utilization and HIV/STI-related outcomes.

    Mona Mittal, PhD

    Faculty Affiliate

    Dr. Mona Mittal is an associate professor in the Department of Family Science, School of Public Health, at the University of Maryland, College Park. Her research interests include physical, emotional, and sexual health of women with a specific focus on psychological trauma, interruption of the intergenerational cycle of violence, and physiological mechanisms linking intimate partner violence (IPV) and adverse health outcomes across the lifespan. In her current work, Dr. Mittal is addressing the synergistic interactions between substance use, violence, and HIV/AIDS that have been closely linked with HIV acquisition in the African American population.

    Lakeshia Watson, MPH

    Graduate Research Assistant

    Lakeshia is currently a Ph.D. student in the Department of Epidemiology and Biostatistics at the University of Maryland, College Park. Previously, Lakeshia has served as an epidemiological research fellow in the HIV Incidence and Case Surveillance Branch at the Centers for Disease Control and Prevention (CDC). Lakeshia received her MPH in Community Health Sciences from the University of Illinois at Chicago and her BS in Psychology from the University of North Carolina at Chapel Hill.Her research interests focus on utilizing a social epidemiological framework to understand the multilevel, social and structural determinants of HIV-related outcomes among vulnerable populations. She aspires to use research to inform policies that affect those living with HIV and those living in communities characterized by high HIV diagnoses.
