Dr Joanna Sperryn-Jones, Senior Lecturer in Fine Art Sculpture Practice, York St John University, UK. Sperryn-Jones makes and breaks sculpture and frequently encourages others to participate in the process. Her sculptural installations are activated through viewers' interaction with the work as they explore experiences of restriction and/or breaking. Her research focuses on experiences of breaking and draws parallels between personal experiences in life, such as breaking bones, with those of making/breaking sculpture, Derrida's concept of the break and breaking as a methodology. Her writing practice also involves breaking and has been developed from the 'cut-up technique' of William Burroughs.
