Johnston has held several teaching and research posts since 2002, including an AHRC Research Fellowship at the University of Ulster, Belfast, investigating issues of ‘trauma of place’. In 2007 she was the Ré Soupault Guest Professor at the Bauhaus University, Weimar. Between 2012-2021 she was joint-lead on the BxNU MFA programme at Northumbria University, England. Currently, she lectures at Ulster University in the Photography & Video Department.

Additionally, she has been committed long-term to exploring collaborative processes of improvisation, facilitating workshop encounters, alongside engaging with the development and sustainability of creative networks.
