Her current research project, in collaboration with Professor Heather Goodall, is called Environments of Fear and Hope: Overabundance, scarcity and the circulation of botanical knowledges through intercolonial networks 1850-1950. In this work, we are tracing the transnational movement of prickly pear Opuntia sp. and saltbush Atriplex sp. (plants, plant material and plant information) between Australia, India, South Africa and America. This comparative study will allow us to identify metaphors of fear and hope in relation to invasive and endangered species with special reference to how such metaphors overlap in human and non-human populations in different places. We are examining the role of emotions in drawing together networks of people and things that facilitated environmental change.
