My research aims to reduce mortality and morbidity in under-served populations in the United States and abroad. The underlying discipline bases for this research are epidemiology, community randomized trials and biostatistics. Areas of focus include (1) maternal, neonatal and child health, (2) nutritional deficiencies and (3) infectious diseases.
Current projects include

1. A randomized trial to test the efficacy of a balanced protein energy supplement for daily use during pregnancy on the outcomes of pregnancy and growth of infants during the first 6 months of life in Sarlahi District, Nepal. 

2. Estimate prevalence and risk factors for preterm, small-for-gestational-age and low birth weight and the impact of these adverse birth outcomes on neonatal mortality in low and middle income countries.

3. Understand the current health system readiness, public trust in health authorities, and COVID-19 vaccine hesitancy to achieve equitable access to and high demand for vaccines as supply increases in Nepal.
