His work questions the politics of space and time through a system-specific, rather than site-specific approach. He is concerned with the hidden structures that pre-determine the limits of our social and political imagination. Through a language of diagrams, drawings and models he explores a hidden landscape of systematic and structural conditions that organise our political sub-terrain. This sub-space is framed by systems which transverse multiple realms (technical, spiritual economic, psychological, etc) and therefore Dennis’ work can be seen as an attempt to stitch these, sometime opposed, sometimes complimentary, systems together. To read technological systems alongside spiritual systems, to combine political fictions with science fiction.

He holds a degree in Architecture from the University of the Witwatersrand, Johannesburg and a Masters of Science in the Art, Culture and Technology from the Massachusetts Institute of Technology (MIT).
