Sebastiaan Loosen studied architectural engineering and philosophy at the KU Leuven. He defended his master theses on the theory of urban violence (entitled ‘War as urbanism, urbanism as warfare. Urbicide in Hebron’, supervised by Lieven De Cauter) and on the spatial aspects of biopolitical theory (entitled ‘Biotope and metropolis. Biopolitical space in the works of Michel Foucault and Antonio Negri’, supervised by Rob Devos and Matthias Lievens). Since 2014, he has been a Ph.D. candidate at the Department of Architecture at the KU Leuven. His current research project is entitled The formation of Architectural Theory in Belgium, 1965-1995, funded by the FWO (Flemish Scientific Research Fund) and conducted together with fellow Ph.D. candidate Elke Couchez and with supervisors Hilde Heynen, Rajesh Heynickx and Yves Schoonjans. His contribution to the project focuses on the publication culture by taking publications as the locus to explore different modes of ‘going public’ with theory, to scrutinize the ‘nature of theory’, its more contingent and minor side as well as the relation of form and content. He is especially interested in how societal changes from the 1960s onwards have their impact on thought and architecture, and in particular in the phenomenon of thinkers addressing postmodernity – understood as an attempt to describe societal traits that would be somehow fundamentally different from modernity.
