    India; United States (2012-2016)
    This project involves the careful mapping of face-to-face social networks in Uttar Pradesh, India, in 80 villages and 100,000 adults. We will examine how the strategic targeting of novel neonatal practices results in more widespread behavior change, and study the inter-personal diffusion of innovation.
