Laurence Kimmel is a Lecturer at the Faculty of Built Environment at the University of New South Wales. She is an architect (MArch, École Nationale Supérieure d'Architecture de Lyon, 1998) and a philosopher of architecture (PhD, University Paris 10 Nanterre, 2006). Her research focuses on boundaries and gradients between public and private space. Her book Architecture as Landscape (2010) describes experiences of architectures as a succession of heterogeneous spaces of different statuses, and shows how architectural shapes mediate the perception of adjacent spaces and the landscape. The objects of her research cover architecture, artworks, landscape architecture, and urban planning, all of which she analyses in a cross-disciplinary way. Her research also addresses the notion of "critical practice": architects who consider and express tensions, paradoxes or contradictions of the socio-political context in their practice.
