I am trained in pediatric infectious diseases and virology and have a particular interest in respiratory viruses and respiratory virus vaccines. At the Center for Immunization Research, we conduct a large number of phase I and II trials of respiratory virus vaccines in adults and children as young as one month of age. In our laboratory, we conduct studies to determine how the immune response to respiratory viruses matures over the life span, with a particular focus on the differences between very young infants and older children. We are also involved in studies of RSV (respiratory syncytial virus) pathogenesis, to determine host and viral factors that may contribute to severe disease. Finally, we are also interested in the epidemiology of respiratory virus infections in resource-poor settings.
