Research Interest
The focus of the research in our laboratory is to study digestion, absorption, and utilization of energy and nutrients in monogastric animals and humans. We determine protein quality in human foods including determination of Protein Digestibility Corrected Amino Acid Score (PDCAAS) and the Digestible Indispensable Amino Acid Score (DIAAS) that is now recommended by FAO for protein evaluation of human foods. We use the pig as a model for humans in this research. We have also determined fermentability of conventional and novel fibers used in human foods using the pig as a model.
