Dave Dallas

David C. Dallas, PhD

Associate Professor, Nutrition

Faculty profile

Dave guides the research team to unravel the biological secrets of human and bovine milk and applies these findings to improving infant and adult health. He is fascinated by how milk’s components, particularly proteins and peptides, are affected by digestion and how these components exert functions within the gut. He is highly motivated to find methods to process milk that enhance safety while best maintaining its incredible bioactivity.
