AREAS OF EXPERTISE

- Immune Health, Human Milk Oligosaccharides, Nucleotides -

Rachael Buck works on the forefront of infant nutrition. As the director of Preclinical Research and 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 designs 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 Research Fellow for her pioneering work. She has authored more than 50 journal articles and filed 55+ patents. Rachael received her PhD degree in immunology from the University of Cambridge, U.K.
