Active Research Projects/Grants
- TLR4 signaling in the pathogenesis of surgical necrotizing enterocolitis
- Mechanisms of Epithelial Restitution in NEC
- Pathogenesis and Treatment of Necrotizing Enterocolitis
- A Novel Role for Enterocytes in the Maintenance of Gut Barrier Function:
Phagocytosis
Current Research Interests
- To understand the mechanisms governing the migration of intestinal
epithelial cells during conditions of
intestinal inflammation, such as necrotizing enterocolitis, Crohn's
disease and infection. This information will hopefully provide novel
therapeutic targets for treating these disorders.
- To understand the mechanisms of phagocytosis of pathogens by macrophages
in neonates during conditions
of inflammation. This information will hopefully provide insights for
enhancing the immune system
during critical illness.
- Initiating a large review of all patients with congenital diaphragmatic
hernia to determine the optimal timing
and mode of surgical repair.
- Initiating a retrospective and prospective review of patients with
tracheo-esophageal fistula to determine the
factors influencing outcome in these patients.
- Retrospective review of patients who have sustained traumatic intestinal
injuries, to determine the optimal
diagnostic modality and to determine strategies to improve their outcome.
