Our global research focuses on maternal and infant vaccinations, optimizing vaccination strategies in the community setting, and improving vaccine immunity.  We do this by studying infant immune development, responses to mucosal vaccination, and the influence of breast milk and gut microbes on immune responses.  Our research starts at the bed side, is taken to the bench, and then back to bed side and community. Our goal is to find strategies to improve vaccine effectiveness and protect vulnerable infants and children from infectious diseases worldwide.
