Applying Unique Statistical Methods for Understanding the Health of Intersectional Racial and Sexual Minority Populations
The laboratory in Prevention and Racial/Sexual Intersectionality Study Methodology is focused on the application of unique statistical methods for understanding the health of intersectional racial and sexual minority populations. We employ latent variable modeling and causal inference approaches to these research questions. Our lab partners with faculty, students, and community-based organizations in the development of research to better promote the health of intersectional sexual and racial/ethnic minority populations, with a focus on prevention. Research topics include HIV/STI prevention, stigma, healthcare access, health behaviors and more.
Rodman Turpin, PhD, is an epidemiologist and analyst focused on HIV prevention among racial and sexual minority populations, particularly how racial and sexual stigma, depression, anxiety, substance use and other social and structural factors affect HIV risk and prevention. He is an HIV prevention trials network postdoctoral scholar and UMD-PRC core research scientist. Additionally, his methodological interests include latent class analysis, latent profile analysis and
structural equation modeling.
