Impacts of early-life nutrition on brain development

As part of my research in the Piglet Nutrition and Cognition Laboratory (PNCL), I use the piglet as a pre-clinical model to assess the impact of early-life nutrition on brain development. My work focuses on the addition of novel compounds to infant formulas in order to determine how these compounds might impact structural and cognitive development. My current MRI work seeks to expand upon our current MRI techniques by developing sequences for contrast-based brain blood volume measures as well as MRI techniques to assess indicators of myelination. Additionally, I am working on development of eyeblink conditioning, a novel associative learning paradigm for the piglet model. This behavioral assessment has proven sensitive to nutritional intervention in other animal models and due to its translational nature will prove useful in pre-clinical infant nutrition studies that utilize the piglet model. Specific areas of infant nutrition in which I am interested include: perinatal choline deficiency, fatty acid metabolism, and prebiotic mediated gut-brain axis maturation.
