In 2007, she was the ‘Ré Soupault’ Guest Professor at the Bauhaus University, Weimar. Currently, Course Leader of the BxNU MFA at Northumbria University in England. In 2013, Johnston published a PhD research project entitled, Beyond Reasonable Doubt: An Investigation into Concepts of Doubt, Risk and Testimony Explored Through Consideration of Performance Art Processes in Relation to Systems of Legal Justice.Several artworks have developed through intensive collaborative processes, most notably over the last decade with Alastair MacLennan and Dominic Thorpe. Additionally, Johnston has been committed long-term to the development of performance art networks.
