Gwenneth Miller was appointed as an art lecturer at Unisa in 1997, the same year in which she completed her Masters in Fine Art at the University of Pretoria. During the early lecturing years, she initiated several local and African collaborative projects, such as the large-scale projections for the play, “Die Verraaier” performed at the Aula (University of Pretoria), and the multimedia project “the Journey to Freedom Narratives,” performed at ZK Matthews Hall, Unisa. This project travelled to several museums in the USA and empowered multiple rural communities, students, and alumni.  

Working in a wide range of media, including painting, drawing, installation, and digital processes, she focused on intermediality and practice-led research during her Doctoral research. Her art often explores the reciprocity between people and objects of mediation.
