Rachael Buck, PhD, is a senior research fellow at ´óÐãÊÓƵ and 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 ´óÐãÊÓƵ nutritionists develop the best infant formula possible. She helps design clinical trials to study the effects of these nutrients on infant development in the first year of life.

Rachael leads ´óÐãÊÓƵ’s pioneering research program for human milk oligosaccharides (HMOs). HMOs are beneficial prebiotics found in breast milk that help support immune and gut health. Clinical research on HMOs has demonstrated improved immunity benefits similar to those experienced by breastfed infants.Ìý
