Dr. Gunaratna’s research aims to identify and evaluate multisectoral interventions, particularly those involving agriculture, that can equitably and sustainably improve nutrition and health outcomes at scale in developing countries.  With a focus on Africa, she has conducted randomized studies and surveys on the effectiveness, consumer acceptance, and strategies for promotion and scaling up of nutrition-sensitive agricultural technologies; evaluation of large-scale integrated nutrition and agriculture programs; and clinical trials on the safety and efficacy of nutrition-specific interventions to reduce the risks of adverse nutrition and health outcomes among neonates, infants, young children, adolescent girls, and women of reproductive age in low resource settings.  Her current work evaluates interventions and technologies such as genetic and agronomic biofortification, promotion of improved livestock, and the use of peer groups to encourage positive behaviors relating to child feeding, early childhood stimulation, sanitation and hygiene, and gender relationships.
