Byron Mason is the Research Partnerships Director for the Technology and Information Exchange (TIE) Core where he facilitates community-engaged research, HIV prevention science, and develops sustainable research collaborations between CAPS scientists and diverse stakeholders both nationally and internationally.  He also serves as Co-Chair of the CAPS Community Advisory Board (CAB) as well as provides a range of technical assistance (TA) to community based organizations, researchers, funders and policy makers.

During the 1990s and early 2000s, Mr. Mason worked at CAPS as Project Coordinator for the Seropositive Urban Men’s Intervention Trial (SUMIT), one of the first “prevention for positives” efforts in the United States. He also worked as Project Director for the Gay Couples Study which sought to examine the range of sexual agreements made within gay male relationships. In 2002 he relocated to Atlanta, Georgia to work for the Centers for Disease Control and Prevention (CDC) where he directed a four-year, multi-site research study focusing on ethnic and race-specific psychological, social, cultural, and environmental variables associated with HIV risk behaviors.

Upon returning to the Bay Area in 2007 Mr. Mason worked for Gilead Sciences and was responsible  for the company’s global collaborative research portfolio which contained numerous academic, federal and industry-sponsored clinical studies including early-phase developments of pre-exposure prophylaxis for HIV prevention (PrEP).
