Obesity Research Working Group
My research focuses broadly on: (1) understanding how maternal and child health are impacted by rising levels of obesity and diabetes in developing countries, (2) determining how the delivery of healthcare impacts the identification and treatment of these diseases during the perinatal period, and (3) developing interventions focused on pregnancy and early infancy to prevent the intergenerational transmission of chronic disease. I have ongoing projects and collaborations in American Samoa, Samoa, South Africa, and the US
Specialized Terms: global non-communicable disease, obesity, diabetes, maternal and child health, pregnancy health, infant feeding, prenatal care
