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. Identify and prioritize modifiable risk factors for stillbirths, preterm and/or small-for-gestational age birth, and early and late neonatal mortality using monthly data from late first trimester through labor and delivery from 3 trials in rural Nepal.

2. Primary data collection to validate maternal recall of receipt of nutrition and other interventions in antenatal care and pregnancy in Nepal.

3. 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.

4. Granular age-specific data analysis of under 5 child mortality patterns using pregnancy and live birth cohorts from low and middle income countries.

5. Estimate global prevalence of preterm, small-for-gestational-age and low birth weight and the impact of these adverse birth outcomes on neonatal mortality.

6. 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.
