Professor Holloway’s research focuses on understanding the multilevel contexts in which health risk and protective behaviors occur in order to inform theoretically driven, culturally tailored structural and social network-delivered interventions to improve the health and well-being of sexual and gender minority (LGBT) communities. He is the Principal Investigator of a study funded by the UCLA Center for AIDS Research to understand health risk behaviors among gay, bisexual and other men who have sex with men in the Dominican Republic. Dr. Holloway is also currently collaborating on two studies funded by the National Institutes of Health. The first, entitled “Social Networks and Technology Use of Transgender Women with/at High Risk for HIV” focuses on understanding how the structure and composition of transgender women’s egocentric social networks influences their engagement in HIV risk and protective behaviors. The second, entitled “Social Media for HIV Testing and Studying Social Networks” examines the efficacy of a Facebook-delivered peer education program on HIV testing behaviors of racially and ethnically diverse gay, bisexual and other men who have sex with men.
