Dr. Fung is an Assistant Research Scientist at the Children's Hospital Oakland Research Institute (CHORI) and an Associate Adjunct Professor at the UC Davis Nutrition Department. She has advanced training in nutrition and a long-standing interest in the impact of nutrition on children with chronic disease.
The complexity of trace element metabolism and the paucity of information that is available for many of the essential trace minerals, particularly zinc, was an initial focus of Dr. Fung’s research. She undertook the first prospective study of mineral metabolism recruiting women prior to conception and following them through weaning their infants. A landmark study, Dr. Fungs’ findings have been cited numerous times in other publications by scientists in the field, and the results were also used to develop the new Dietary Reference Intakes for zinc during pregnancy and lactation (Institute of Medicine, 2001).
More recently, particular areas of concentration have included the assessment of energy expenditure, dietary intake, growth and body composition, bone density and trace mineral metabolism (zinc, iron, copper) in a variety of chronic pediatric disorders including cerebral palsy, cystic fibrosis, vitamin D deficiency rickets, sickle cell anemia and thalassemia. Her most recent NIH funded project is a placebo controlled clinical trial to test the effect of zinc supplementation on bone health in patients with thalassemia.
Dr. Fung was the Helen M. Shearer Endowed Term Professor of Nutrition at the University of Pennsylvania (1998-2000) and a Dannon Nutrition Leadership Institute recipient in 1999. She has published over 40 peer-reviewed articles and book chapters and is an Editor of the first textbook related to the assessment of pediatric bone health, Bone Densitometry in Growing Patients: Guidelines for Clinical Practice Humana Press, 2007.
