My research focuses on the reduction of morbidity and mortality in underserved pediatric populations worldwide. I apply epidemiology and biostatistics to facilitate the development of effective disease prevention and control strategies for pediatric infectious diseases. My research scope includes the following areas: (1) respiratory infections,(2) the interaction between micronutrient status, infection and immunity, (3) nutritional interventions, (4) nutritional immunology, (5) nutrient regulation of host-pathogen interactions, (6) antimicrobial resistance, and (7) mHealth
