Dr.  Phillip Schnarrs

Assistant Professor
Kinesiology, Health, and Nutrition



Since 2007, Dr. Schnarrs has been conducting, presenting and publishing research on HIV prevention and sexual health in high HIV-risk populations. My work has been highly collaborative; integrating clinical sciences, social research and community-based participatory frameworks.

In 2012, he received his Ph.D. in Health Behavior from Indiana University. His studies focused on health services and patient-centered outcomes in the context of sexual health promotion. Dr. Schnarrs’ current work uses a community-based approach to examine primary HIV prevention — specifically researching awareness, access, and adherence to pre-exposure prophylaxis (PrEP) by identifying points of intervention across the PrEP cascade and factors influencing uptake and adherence. Over the past five years, he has published more than 20 manuscripts, presented research at several national conferences and received funding to design, implement and evaluate community-level HIV-prevention interventions, including novel approaches to PrEP uptake.

In 2014, he co-founded the South Texas Consortium for HIV and STI Research, bringing together HIV researchers, healthcare providers, and community members to address South Texas’ sexual health needs. PrEP Access San Antonio (PASA) developed out the South Texas consortium with the goals of increasing PrEP awareness, access, and adherence. PASA coordinates efforts and standardizes processes across San Antonio’s health department, AIDS Service Organizations (ASO) and Federally Qualified Health Centers (FQHC).
