She identified a role for estrogen receptors in colon cancer risk. This work was funded in part by the NIH-sponsored University of Missouri Botanical Center, USDA and AICR. In other work funded by the USDA, she studied the cellular role of zinc in regulation of growth and food intake. While at the University of Missouri, she taught courses in nutritional biochemistry, sports nutrition and food science. At ISU she teaches a graduate course in nutritional oncology and an undergraduate course in food systems. She developed service learning curricula for undergraduate nutrition and dietetic students funded by the Lance Armstrong Foundation and the American Cancer Society.
