Dr. David Dallas is an Assistant Professor in the School of of Biological and Population Health Sciences within the College of Public Health and Human Sciences at Oregon State University in Corvallis, Oregon.

The overall aim of Dr. Dallas’s research is to improve the health of premature infants, a population that suffers greatly reduced health outcomes (including early mortality, developmental disorders, and high risk of infection) in comparison with term-delivered, breast milk-fed infants. The reduced digestive capacity of premature infants results in an inability break down milk proteins in the same way as term infants. This diminished digestive function may result in the premature infant's inability to take advantage of bioactive peptides and glycopeptides encrypted in human milk proteins. In essence, premature infants are not receiving the full and multi-faceted health benefits of milk.

Dr. Dallas attended graduate school at UC Davis in the Nutritional Biology Graduate Group, graduating with his Ph.D. in 2012. From 2012 to 2015, he was a post-doctoral fellow at UC Davis. Dr. Dallas’s doctoral and postdoctoral research focused on the characterization of the human milk glycans and human milk protein digestion in infants. Methods developed allowed for the identification of thousands of naturally occurring peptides released from milk proteins by native milk enzymes. His work showed that milk enzymes continue to break down milk proteins within the infant's stomach to release functional peptide fragments. His graduate research was funded by the Designated Emphasis in Biotechnology with the NIH Training Program in Bio-molecular Technology and the National Science Foundation Graduate Research Fellowship, and his post-doc was funded by the USDA NIFA program and the National Institutes of Health K99/R00 Award. 

Dr. Dallas grew up on a wheat farm in Pendleton, Oregon. He graduated from Rice University in Houston, Texas with a BA in Public Health in 2008.

University of California, Davis (Davis, Calif.)

Department of Food Science and Technology

June, 2012 – December, 2015

Fellowship provided by USDA National Institute of Food and Agriculture and the National Institute of Health K99 Career Award. Research to identify the digestive products of breast milk in term and premature infants in order to determine improved feeding solutions for premature infants. Examining bioactivity of identified naturally-occurring peptides in milk. Dr. Dallas has identified over 500 novel milk peptides, of which, over 50 which have potential antimicrobial or immunomodulatory affects. His in vitro work shows that these peptides kill several strains of harmful bacteria. Peptide identification with microchip liquid chromatography high-resolution mass spectrometry and database searching. Mentors: Dr. Carlito B. Lebrilla, Dr. Daniela Barile, Dr. J. Bruce German and Dr. David Mills

Ph. D. Student

University of California, Davis (Davis, Calif.)

July, 2008 - May, 2012

Dr. Dallas's research under Dr. J. Bruce German aimed to determine the composition of human milk N-linked glycans, peptides and glycopeptides. The aim of this research was to determine biological differences between premature and term mother’s milk and digestion variability in term and premature infants so that an approach could be established for improved feeding of premature infants.
