Farming is a practical activity, messy and material. It involves interactions between people, technologies, animals, and natural forces. I'm working on the heterogeneities of those interactions; how animals, devices and people interact with one another. Within this general interest I'm currently attending to the Cattle Tracing System. The methods I use in thinking about this come expecially from STS (Science, Technology and Society) and are material-semiotic in character: this is a sensibility informed by actor-network theory and feminist technscience studies.
