We are a US National Science Foundation-supported network of scientists, industry leaders, and policy partners committed to building better cities. We examine physical changes in the scale and scope of infrastructure design, the role of new technologies, as well as the changes in public attitudes and policy that can help achieve the infrastructure transitions needed to build healthy, sustainable, and livable cities today and in the future.
