Rachael Buck, PhD

Senior Research Fellow, Global Research and Development
Abbott Nutrition
Columbus, OH, USA
Rachael Buck works on the forefront of infant nutrition. As a discovery scientist in the field of immune health, Rachael studies the components of breast milk to help Abbott nutritionists develop infant formulas that are as close as possible to breast milk. She helps design clinical trials to study the effects of these nutrients on babies’ development in the first year of life. Rachael leads the pioneering research program for human milk oligosaccharides (HMOs). HMOs are beneficial, prebiotic- like nutrients found in breast milk that help support immune and gut health. Abbott has driven the clinical research behind HMOs for more than 20 years, paving the way for this breakthrough ingredient to be added to infant formulas. The research on HMOs has demonstrated improved immunity benefits similar to breast-fed infants. Rachael joined Abbott in 1995 and over her career has received numerous prestigious Abbott awards for her research on nucleotides, pediatric immunity and HMOs. She was also named a Senior Research Fellow for her pioneering work. She has authored more than 50 journal articles and has over 120 granted patents. Rachael received her PhD degree in immunology from the University of Cambridge, UK.
