Alfonso Galderisi, MD, PhD, is a pediatric endocrinologist who completed his training in Italy at the University of Padova. At the university of Padova he conducted the first trial using continuous glucose monitoring to adjust glucose intakes of very preterm infants, followed by a large Cooperative European Study aimed to identify the effects of early glucose changes on neonatal brain.

During his research fellowship at Yale University in 2016 he worked on the role of the incretins as determinants of beta cell function in children with obesity. More recently, by the use of metabolic modelling, his research focused on the physiopathology of insulin sensitivity and secretion in the early stages of T1D. His research areas include the physiology of insulin secretion and sensitivity in children with T1D and T2D and the early neonatal glucose metabolism. His research had been supported by the European Commission (while he was assistant professor of Pediatrics in Italy) and by the Juvenile Diabetes Research Foundation.
