Pediatric nutrition with an emphasis on optimizing intestinal function in healthy and compromised neonates.
The early neonatal period is a critical phase of development during which time nutrition can exert both short and long-term effects. Human milk is the optimal form of nutrition for the human infant; however, most babies in the U.S. are not breastfed or only receive breast milk for a short period of time. Formulas provide adequate nutrition, but differ in nutrient composition from breast milk and do not contain the bioactive components (e.g. hormones and growth factors) that are present in breast milk. How these various components influence development and their long-term consequences is largely unknown. Therefore, our research program is directed at understanding the regulation of neonatal development by components present in human milk and infant formula. A primary focus in the laboratory is on neonatal intestinal development and the development of clinically-efficacious therapies (including optimized formulas) to enhance gut function of neonates. We utilize a variety of porcine models of human disease, including parenteral nutrition, rotavirus diarrhea and inflammation. A recent focus in the laboratory is on the impact of human milk oligosaccharides and synthetic prebiotics on intestinal development and gene expression.
