Jere D. Haas is the Nancy Schlegel Meinig Professor Emeritus of Maternal and Child Nutrition in the Division of Nutritional Sciences, College of Human Ecology, at Cornell University, in Ithaca, New York. He is also International Professor of Nutrition in Cornell's College of Agriculture and Life Science, and Professor of the Graduate School. He received his Ph.D. in Biological Anthropology from the Pennsylvania State University and has been on the Cornell University faculty for 44 years. He conducts research on the functional consequences of iron deficiency on physical and cognitive performance. The emphasis is on the effects of moderate iron deficiency on various aspects of physical performance and behavior in children and young women and how measures of performance relate to everyday productivity and social and economic well being. He also conducts research on food based interventions to reduce micronutrient malnutrition. Professor Haas conducts research on these and related topics in maternal and child nutrition in the United States, China, Mexico, the Philippines, Rwanda and India. Professor Haas served as vice-president and president of the American Association of Physical Anthropologists and on the Expert Advisory Panel for Nutrition of the World Health Organization and the Technical Advisory Group on Food and Nutrition of the Pan American Health Organization. He served as Director of the Division of Nutritional Science at Cornell from 1998 to 2003.
My research deals with nutrition problems of women and young children, with a primary emphasis on iron deficiency and protein and energy under nutrition in developing countries. For 45 years my research has focused on understanding the functional consequences of malnutrition on physical performance, physical activity and behavior. Recent field-based and laboratory studies were designed to identify useful functional indicators that can be used to evaluate nutrition interventions that are designed to improve iron status in women and children.
We are currently examining the efficacy of biofortification as a novel approach to improving dietary iron intakes by enhancing the micronutrient quality of staple food crops such as rice, pearl millet and beans in collaboration with conventional plant breeders. These staple foods are consumed by a large number of the most nutritionally vulnerable population groups in Asia, Africa and Latin America. This research has shown that biofortification strategies can improve the iron status of human subjects at risk of deficiencies in developing countries. In addition to the impact of biofortification on iron status, our research group has also demonstrated that physical work capacity, physical activity and cognitive function are also improved with the improvement in iron status through biofortification in India and Rwanda.
