Joshua Newell Core Staff, Assistant Professor

Dr. Newell's research can be divided into two primary areas of interest. The first, Metabolisms of Urban Infrastructure and Form, focuses on structural features of the urban form (e.g. built environment, transport, energy, and water infrastructure) that due to their durability have long-term implications for resource consumption patterns and processes within and outside of urban areas. The second research area, "Ethical" Urban Consumption and Commodities, focuses on the interrelationships between the consumption of consumer products, our responsibilities as global ‘green’ urban citizens, and the role of governance mechanisms and frameworks (including local institutions) in regulating product consumption. His research approach is often multi-scalar and integrative and, in addition to theory and method found in geography and urban planning, he draws upon principles and tools of industrial ecology (e.g. footprinting and life-cycle analysis), and spatial analysis (e.g. land use/land cover change).
