During the next 10-12 months, Achsah will be collecting data in Peruvian clinics and households in order to explore the biological and cultural connections between iron deficiency and infection, the gut microbiome, and home environment in children living in a peri-urban community in Lima. Support for her field research comes from the National Science Foundation, Lewis and Clark American Philosophical Society, Sigma Xi Scientific Research Society, and the Frank Porter Graham Child Development Institute.
