Philosophy of Care
Caring for a premature or sick newborn requires a team of dedicated professionals. I love working with parents, nurses, pharmacists, respiratory therapists, dietitians, social workers, and specialists to provide the very best care for these fragile little guys.
Dr. Underwood's clinical activities are in the care of premature and sick newborn infants. His research interests include necrotizing enterocolitis, development of intestinal innate immunity, and mechanisms of probiotics and prebiotics in pre-term infants.
Research projects include clinical trials of probiotics and prebiotics in premature infants, assessment of Paneth cell antimicrobial expression in infants with necrotizing enterocolitis, and evaluation of Paneth cell expression in newborn rats.
Dr. Underwood's research is focused on prevention of common health problems of very premature infants, including necrotizing enterocolitis, sepsis, and poor growth after birth.
This includes discovery of the mechanisms by which human milk protects the intestinal tract, and how human milk and probiotics work together to shape the composition of the intestinal microbiota and influence the baby's developing immune system.
