I am a biosocial anthropologist broadly interested in how local environments shape biology, health, and perceptions of health in a globalizing world. I interrogate proximate mechanisms underlying infant health and development, such as the microbiome, as well as the social and political-economic contexts that shape health and metabolic disease risk. My research program investigates how dietary shifts, antibiotic use, and infant care practices affect infant growth through maternal and infant microbiomes in Samoa.
