Unraveling the biology of human and animal milk
We specialize in the following areas
![bioactive milk peptides](/sites/health.oregonstate.edu/files/styles/fluid_webp/public/2023-10/bioactive_milk_peptides-400px.jpg.webp?itok=hVcaMLc2)
Bioactive milk peptides
Identifying novel bioactive protein fragments—peptides—in human and bovine milk
Identifying which milk peptides are present across the digestive tract (infants and adults)
![bioactive milk proteins](/sites/health.oregonstate.edu/files/styles/fluid_webp/public/2023-10/bioactive_milk_proteins-400px.jpg.webp?itok=ESgObOam)
Bioactive milk proteins
Determining which milk proteins survive intact across digestion, enabling them to exert function throughout the gut
Improving protein preservation across milk processing
![improving preterm infant health](/sites/health.oregonstate.edu/files/styles/fluid_webp/public/2023-10/improving_preterm_infant_health-400px.jpg.webp?itok=rMtlxLVE)
Improving preterm infant health
Assessing digestive deficiencies in preterm infants
Improving processing of human milk to enhance bioactivity
![improving adult health](/sites/health.oregonstate.edu/files/styles/fluid_webp/public/2023-10/improving_adult_health-400px.jpg.webp?itok=1VHGjm0d)
Improving adult health
Assessing the survival of functional bovine milk proteins and peptides across adult digestion
Assessing the effect of bovine milk proteins and peptides on health (e.g., immune system, microbiome)
Improving processing of bovine milk components to enhance bioactivity
Our approach
Clinical studies
- Collecting digestive fluids from infants and adults
- Feeding studies
Digestion models
- Static and dynamic simulated infant and adult digestion
Structural analysis
- Peptidomics
- proteomics
- Glycopeptidomics
- Enzyme-linked immunosorbent assays
Functional assays
- Immunomodulatory assays (e.g., macrophage cell culture)
- Intestinal cell culture
- Antimicrobial assays
