Benjamin is Assistant Professor of Bioresource Engineering and head of the Sustainable Urban-Rural Futures (SURF) lab at McGill. He is interested in understanding how urban activities produce environmental change both inside and outside cities. He develops methods and tools to quantify the scale of these changes and the locations where they occur using life cycle assessment, input-output analysis, and geospatial data. Benjamin is particularly interested in combining quantitative methods with theory rooted in social science to explore multiple dimensions of sustainability and address issues of distributive justice. His topical foci include urban food systems (esp. urban agriculture), agri-commodities, residual resource engineering, sustainable production and consumption, and energy systems.
