Complex human-environment systems. Transformation of the earth's social and ecological systems is occurring at a rate and magnitude unparalleled in human experience. Many attendant challenges, such as feeding growing populations or dealing with global environmental change, are manifestations of complex human-environment systems. Dr. Manson advances knowledge in a variety of research areas, including interactions among agriculture, population, and institutions; and urban issues including disease, environmental, and residential mobility. The Ecological Society of America recognized this cholarship with the Sustainability Science Award for 'outstanding contributions to sustainability science.
Spatial Science. Spatial science examines spatial phenomena, processes, and patterns through technologies such as computer mapping and mathematical modeling. Spatial computing brings together data from an array of sensors, ranging from GPS units in mobile phones to satellite-based cameras, on a range of human and environmental systems. Dr. Manson ublishes extensively in this area with a focus on spatial big data and in methods arising from the complexity sciences, such as agent-based models and cellular automata.
Cyberinfrastructure and Big Data. Scholars interested in a wide array of social, natural, and human-environment questions face a dearth of detailed, multidecadal, global-scale data. In response to these data needs, Dr. Manson and colleagues conduct cyberinfrastructure for ‘gold standard’ research data on population, socioeconomics, health, and environment. Scientists increasingly use 'big data', or very large data sets and attendant analysis approaches, to understand an enormous array of phenomena, ranging from social networks on the internet to large scale deforestation.
National Historical Geographic Information System (NHGIS) is the nation's most comprehensive source for census data, geographic data, and metadata describing population characteristics of American regions, places, and neighborhoods from 1790 to the present. NHGIS is the largest publicly accessible population database in the world and is an essential component of the shared data infrastructure for population and health research. NHGIS is supported by:

International Historical Geographic Information System (IHGIS) is the International Historical Geographic Information System, which provides data tables from population and housing censuses as well as agricultural censuses from around the world, along with corresponding GIS boundary files. Data from diverse published documents are provided in a standardized, ready-to-use structure with thorough, consistently formatted metadata.
