Ruanne Barnabas is an Associate Professor in Global Health and Medicine at the University of Washington and affiliate at the Fred Hutchinson Cancer Research Center. She is a South African Physician-Epidemiologist. Her research focuses on interventions for HIV and STD treatment and prevention, and, more recently on COVID-19 prevention. She is the protocol chair of the Delivery Optimization for antiretroviral (DO ART) Study, which will evaluate the effectiveness and cost-effectiveness of decentralized, community-based ART initiation compared to clinic- based care. Also, she is the Principle Investigator for the COVID-19 PEP Study. She is the protocol chair for the Kenya Single-dose HPV vaccine Efficacy (KEN SHE) Study, which will evaluate the efficacy of single-dose HPV vaccination for women. She leads the cost-effectiveness evaluation of other projects including scale-up of cervical cancer and HIV treatment and prevention in high burden settings. Her projects use clinical trial data and health economic modeling to estimate the potential impact of interventions. The ultimate aim of her work is to identify effective and efficient treatment and prevention public health strategies.
