Faculty Information


Dr. Barnabas is an Infectious Disease Physician-Scientist at the University of Washington and affiliate at the Fred Hutchinson Cancer Research Center. Her research focuses on HIV treatment and prevention, specifically on interventions that reduce HIV viral load and, consequently, disease progression and transmission. Her projects use both empiric data and mathematical models to better understand HIV clinical progression and transmission, and estimate the potential impact of HIV interventions at population level. The ultimate aim of her work is to estimate the effectiveness and cost-effectiveness of HIV treatment and prevention interventions to inform clinical trial design.
