Brief Biography

Dr. Reback is a Senior Research Scientist with Friends Research Institute, was the Founder and Executive Director of Friends Community Center, the community-based research site for Friends Research, a Researcher in the Department of Family Medicine at the UCLA David Geffen School of Medicine, and the Director of the Combination Prevention Core for the UCLA Center for HIV Identification, Prevention and Treatment Services (UCLA CHIPTS).

Throughout her career, the focus of Dr. Reback’s research has been the examination of the intersection of substance use disorders and HIV risk behaviors among sexual and gender minority individuals. Dr. Reback has an extensive and established scientific career designing, implementing, and evaluating large-scale HIV prevention and treatment clinical trials including behavioral and biomedical treatment therapies, technology-based and mHealth interventions, qualitative and quantitative mixed methods research, venue- and street-based programs, and conducting community-research collaborations through community-based participatory research. In collaboration with several local, national, and international community-based organizations, Dr. Reback has used implementation science methodology to adopt, tailor, and transfer her evidenced-based interventions into public health and community settings. One significant aspect of Dr. Reback’s work has been the early identification of gaps in scientific inquiry and identifying emerging areas of research. In 1995, she began working in the field on trans health disparities and was the Co-investigator on the first epidemiological study in Los Angeles County to assess health risks and health care utilization among trans women. Also, in 1995, she was among the first researchers in the United States to identify the associations between HIV infection and methamphetamine use among sexual minority men.

Dr. Reback’s community and policy work includes current and past membership on numerous local and national HIV/AIDS and substance use task forces and advisory committees. She has authored/co-authored approximately 150 scientific publications, and has been the recipient of several awards in recognition of her scholarly and community work.
