Elizabeth Johnson is Assistant Professor of Human Geography at Durham University. She is a writer, researcher, and educator studying how new ties between the biosciences and technological innovation are changing how we understand life in the context of environmental precarity. She writes on developing fields like biomimicry, biosensing, and biotechnology and their influence on how we inhabit our environment. Currently, she is researching the interface between marine science and policy with a focus on tensions between marine conservation and the emerging Blue Economy. The work examines how marine organisms and the materials extracted from them pass through, across, and into the different ecological and epistemological worlds to figure in the production of healthy publics, ecological futures, and promissory economies.
