Pediatric gastroenterology


Undernutrition; diarrheal diseases; environmental enteropathy; intestinal stem cells

The Gastroenterology, Hepatology and Nutrition laboratory is broadly interested in the reciprocal cycle of childhood diarrhea and malnutrition, with a current focus on the mechanisms of a promising glutamine-based oral rehydration and nutrition therapy. Using cellular and molecular techniques in both cell culture and an infant mouse model of undernutrition, we study the role of EGFR -- a key regulator of intestinal homeostasis -- in glutamine’s benefits for intestinal health.

In addition, we participate in epidemiologic studies of early childhood diarrhea and undernutrition with colleagues at the Federal University of Ceará in Fortaleza, Brazil and the University of Virginia.
