SFI's Cities, Scaling, and Sustainability research effort is creating an interdisciplinary approach and quantitative synthesis of organizational and dynamical aspects of human social organizations, with an emphasis on cities. Different disciplinary perspectives are being integrated in terms of the search for similar dependences of urban indicators on population size - scaling analysis - and other variables that characterize the system as a whole. A particularly important focus of this research area is to develop theoretical insights about cities that can inform quantitative analyses of their long-term sustainability in terms of the interplay between innovation, resource appropriation, and consumption and the make up of their social and economic activity. This focus area brings together urban planners, economists, sociologists, social psychologists, anthropologists, and complex system theorists with the aim of generating an integrated and quantitative understanding of cities. Outstanding areas of research include the identification of general scaling patterns in urban infrastructure and dynamics around the world, the quantification of resource distribution networks in cities and their interplay with the city's socioeconomic fabric, issues of temporal acceleration and spatial density, and the long-term dynamics of urban systems.

Learn more about the system dynamics lab at Washington University in St. Louis. We are experts in developing simulation models of problems facing complex social systems. A resource for students, professionals, and researchers, we help build the capacity of those who want to learn and apply system dynamics in order to understand and address specific problems within an organization and community. Our Research Our research includes a focus on understanding the role of social determinants at the community level, identifying strategies for reducing disparities, and informing implementation, scale-up and sustainability of evidence based interventions. Application areas include community responses to intimate partner violence, mental health, natural resources, obesity, cancer, child and maternal health, financial inclusion, K-12 education, and juvenile/criminal justice. Community Engagement We are actively involved in advancing participatory group model building (GMB) methods in diverse communities including both international and domestic settings. Teaching We are invested in building capacity in system dynamics among the next generation of researchers, policy makers, and social innovators. The lab offers a sequence of graduate level courses that prepare students to tackle dynamic social problems with innovative, design-driven, transdisciplinary solutions.
