My current research focuses on sustainable cities, urban forestry and representations of nature in the construction of a range of environmental issues. Within the area of sustainable cities I am researching the potential to develop Industrial Ecology, the use of metrics such as Ecological Footprints and migration issues such as the tree-change phenomenon in Australia. My research on nature includes human-animal relations, particularly thoroughbred breeding and the uses of nature. My work combines urban environmental history with policy and planning research that is future-oriented.
