My research focuses on the health and evolutionary implications of mother and offspring nutrition. In my research, I combine epidemiological, biomarker and ethnographic methods to investigate biocultural pathways to malnutrition. I am particularly interested in clarifying why some nutritional deficiencies and health issues persist today despite decades of public health intervention efforts. I address these issues through hypothesis testing, guided by evolutionary biological and social theories, using data collected in community settings. I am also interested in the applicability of clinical research methods to anthropological studies in resource-limited low-income country settings. My laboratory is a biosafety level-2 facility located in Giltner Hall of MSU. I enjoy working with undergraduate and graduate students in my lab. Past student projects include: “The effect of maternal vitamin A status on secretory immunoglobulin A secretion into breast milk” by Janine Baranski, “Pathways between food insecurity and serum folate status through coping strategies” by Allison Apland, “Feasibility study for iron status dried blood spot assay” by Jonah Stone, “Pilot study of alkaline dissolution of human milk iron assay” by Nerli Paredes Ruvalcaba (working with Dr. Guillaume Girard of ICP-MS Lab, Earth and Environmental Sciences), and “Differences in maternal prolactin levels in relation to infant sex, breastfeeding status, and nutritional status” by Emma Bignall.
