Webel Lab HIV Data Repository

Stock photo of books and laptop computer

The Webel Research Lab created and maintains an HIV Biobehavioral Data Repository which stores de-identified demographic, behavioral, psychosocial, structural, medical chart abstraction, biological data, and frozen specimens in more than 300 adults living with HIV over 6 waves of data collection. To help advance science, we have recently added approximately 100 well-matched HIV uninfected adults to the Data Repository.

New participants are added regularly and we welcome collaborations with new investigators to answer important HIV-related research questions.
