Our group is focused on the understanding how neonatal mucosal immunity develops and its role in the pathogenesis of diverse diseases such as sepsis, preterm labor, necrotizing enterocolitis (NEC) and very early onset IBD (VEO-IBD).
In order to improve our understanding of mucosal immunity, we use a number of single cell based techniques including mass cytometry or CyTOF) to understand diverse interactions between the immune and epithelial components of the GI tract both during development (from fetal to adult tissue) as well as in disease. In addition to continuing studies on GI immune development in infants and young children, currently my lab is applying these techniques to gain a better understanding of placental immune development and postulate that there are potential infection independent immune triggers in the placenta that induce preterm labor and set up a proinflammatory cascade in the infants.
