Dr. Barnabas is an Infectious Disease Physician-Scientist at the University of Washington and affiliate at the Fred Hutchinson Cancer Research Center. She completed her medical training at the University of Cape Town, her doctorate in mathematical modeling at the University of Oxford, and her Infectious Diseases training at the University of Washington. Her research focuses on HIV treatment and prevention, specifically on interventions that reduce HIV viral load and, consequently, disease progression and transmission. She also works on HIV co-infections, including HPV. Her projects use empiric data and mathematical models to better understand HIV and HPV clinical progression and transmission, and estimate the potential impact of interventions at population level. The ultimate aim of her work is to estimate the effectiveness and cost-effectiveness of HIV and HPV treatment and prevention interventions to inform public health policy.
