Walter Gómez, Research Assistant
Walter Gómez has been working on HIV research for close to seven years. He has worked on topics ranging from masculinity, violence, institutional and cultural stigma, and organizational readiness for intervention implementation, among others. This has allowed him to experience the causes, effects, and possible solutions for this epidemic from both micro and macro contexts. Walter is currently a Doctoral student in the Sociology program at UCSF. His upcoming dissertation will explore the ways in which race/ethnicity, culture, and power intersect in the process of design and deployment of risk-management strategies around HIV and drug use, within the context of MSM sex work. These themes should overlap with his proposed work in the Gay Couples Study, regarding the power dynamics within inter-racial couples, as they concern HIV prevention.
