Research Description: 

Dr. Harris has developed a multidisciplinary approach to study the molecular virology, pathogenesis, immunology, epidemiology, clinical aspects, and control of dengue. Her work investigates viral and host factors that modulate disease severity and immune correlates of protection and pathogenesis, using in vitro approaches, animal models, and research involving human populations. In vitro studies have focused on functional characterization of antibodies and B cell memory response, virus-host interactions and viral pathogenesis, viral fitness and evolution, and the mechanism of DENV translation and replication. The mouse models developed by her group recapitulate many aspects of human dengue disease and immune response, including antibody-dependent enhancement of DENV infections, and are being used to identify antibody determinants of protection, enhancement, and therapeutic efficacy. Her international work focuses on laboratory-based and epidemiological studies of dengue, chikungunya and influenza in endemic Latin American countries, particularly in Nicaragua. Long-term collaborations include clinical and biological studies of severe dengue through a 17-year pediatric hospital-based study, a 12-year pediatric cohort study of dengue, chikungunya and influenza transmission in Managua, and a recently concluded cluster randomized controlled trial of evidence-based community-derived interventions to prevent and control dengue.
