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, (3) nutritional deficiencies and infectious diseases, (4) eye diseases and blindness prevention.

Current projects include

1. A randomized trial to assess the impact of newborn massage with mustard seed versus sunflower seed oil on neonatal morbidity and mortality in rural Nepal.

2. A randomized trial to assess the impact of maternal influenza vaccination on respiratory infections in mothers and infants in Sarlahi, Nepal.

3. An observational study to determine if auxiliary nurse midwives can be trained to evaluate non-cephalic presentation, multiple gestation and placenta previa accurately in the 3rd trimester using portable ultrasound in rural Nepal.           

4. Pertussis incidence, risk factors and maternal antibody transfer among young infants in rural Nepal.

5. Step wedge trial to assess the impact of improving cook stoves to reduce indoor air pollution and respiratory infections in young children in rural Nepal.
