Clemens Winkler is a postdoctoral design researcher at the Cluster of Excellence “Matters of Activity. Image Space Material” at Humboldt-Universität zu Berlin. His work relates environmental concerns with social, scientific and technological development. By questioning atmospheric control with its epistemic foundations and institutional affiliations, he, for example, puts clouds into boxes to show what cannot be contained and therefore explores the human obsession with controlling the environment. Opening up participatory and playful frameworks through material transitions becoming intellectual and intimate markers led to his current position as visiting professor for the MA studio “Spiel und Objekt” at the University of Theatre Arts Ernst Busch Berlin.
