Research and Professional Experience

My research interests are focused on identifying effective, low-cost interventions to improve infant, child and maternal nutrition, health and survival in developing country contexts.

This research has been carried out through the Nepal Nutrition Intervention Project - Sarlahi (NNIPS) in the lowlands of Nepal, near the border with the Indian state of Bihar in a series of large community trials of micronutrient supplementation, with nested studies also investigating the effects of chlorhexadine wiping and cord care on infant survival, as well as ethnographic studies of local beliefs and practices relating to development of micronutrient deficiencies.
