Dr. Haymond's research focuses on the substrate and hormonal regulation of glucose and nutrient metabolism in children and adults. Dr. Haymond and his collaborators have investigated the impact of dietary fat, carbohydrate, and fructose content on nutrient oxidation, insulin sensitivity, and glucose homeostasis in normal children, and are extending these studies to obese children. In addition, Dr. Haymond is exploring the regulation of nutrient homeostasis in lactating women, and the hormonal and substrate factors that regulate gene expression in human mammary epithelium. Ongoing studies aim to determine (a) the timing and regulation of the transcriptional event that result in the induction of lactogenesis and production of other milk components in normal mothers, mothers with premature infants, teenage mothers, and obese mothers; (b) regulation of hepatic gluconeogenesis and the impact of fructose and galactose metabolism; and (c) regulation of gluconeogenesis in infants and children with and without type 1 or type 2 diabetes. The ultimate goal of this research is to improve the care and nutrition of neonates and to improve the metabolic control of children with hypoglycemia as well as those with both type 1 and type 2 diabetes.
