Expert’s laboratory studies calcium metabolism during life stages of high demand, i.e., building peak bone mass during adolescence and bone loss in postmenopausal women. Calcium needs in adolescence is investigated with metabolic research camps (Camp Calcium). Dietary alternatives to estrogen replacement therapy for postmenopausal women are also being investigated in her laboratory by a novel approach of Ca-41 technology. Expert uses isotopic tracer techniques to intrinsically label foods or salts of interest in order to study factors that enhance or inhibit absorption and their biological fate in animal models or humans. She has screened many food sources for calcium bioavailability, and has developed rat models for studying calcium kinetics and bone strength. In addition, evaluating enhancers and inhibitors of calcium absorption by active and passive routes is a focus of on laboratory.
Expert may consult nationally and internationally, and is also local to the following cities:
