The use of epidemiology and qualitative methods to develop knowledge for interventions to improve the nutrition of the poor; improving the effectiveness of programs and policies through evaluation and nutritional surveillance. Specifically I participate in research on evaluating the effectiveness of iron fortification in Haiti and China in children including the likelihood that the delivery systems used will result in the same impact as the programs are expanded. I have been involved with developing the construct and use of Program Theory also called Program Impact Pathways (PIP) in planning, implementing and evaluation programs in Mexico, Haiti and Peru.
Validate and institutionalize the reality of the synergies of malnutrition with illnesses on growth and mortality, as these affect programs and policies. Develop the used of Program theory in the planning, implementation and evaluation of nutrition programs
Outreach and Extension Focus
My principal interests are in designing, developing, and testing interventions and strategies to improve maternal and child nutrition in developing countries. Thus, much of my research has focused on elucidating the nutritional determinants of health, performance, and survival in mothers and in children from conception through childhood. The major outcomes I have studied include fetal, infant, and child growth; fetal, infant, and child morbidity and mortality; maternal body composition, lactation performance, and duration of postpartum amenorrhea and subfertility; and anemia and vitamin A nutrition. I have developed and tested nutritional surveillance systems that can trigger interventions to prevent famines, and more importantly to help design policy to improve nutritional status. My expertise is also pertinent to U.S. domestic nutrition and health and some of my work relates to hunger and nutritional interventions in the U.S.A. These interests are developped in retirement by presentations, mentoring and participating in research at Cornell, at the International Food Policy Research Institute, at the Mexican National Institute of Health and the World Health Organization
(WHO), by participating in conferences, and by serving on policy venues such as the WHO Expert Committee on Nutrition, and the Board of Helen Keller International, an international non-governmental humanitarian organization
