Dr. Brennan’s research focuses on HIV and STI risk and resiliencies for GB2M. He examines the ways in which GB2M who are marginalized by gender identity, race, age, HIV status and other social identities access health and social service information and services. His studies have examined resilience among Two-spirit gay and bisexual men who have been living long term with HIV, the intersection of racism and body image among racialized GB2M, the psychosocial factors affecting people living with HIV as they age, and the broad health needs of GB2M who use mobile apps for socio-sexual and educational/informational reasons.
