Maart holds an M.A. in Fine Arts from the University of the Witwatersrand and an M.Sc. in Biotechnology achieved with distinction from Rhodes University. This academic background, along with a growing interest in ruin porn in relation to climate change politics, forms the basis of his artist-in-residence at the University of Johannesburg’s new BioArt Facility in the Faculty of Arts, Design and Architecture (FADA).
