LATTS is a multidisciplinary research centre exploring the emergence and evolution of the complex sociotechnical systems that support, or “infrastructure”, modern societies, with a particular interest in networked infrastructures: the systems handling the material and informational flows upon which societies increasingly rest. For doing so, LATTS researchers have privileged a mesoscopic approach centred on relevant organizations: the sociotechnical organizations operating these systems and the productive, territorial or political organizations dependent upon these systems. Collectively, they have cultivated a spatial orientation; i.e. a specific interest for the organization of space and the management of spatialized organizations. Over the years, LATTS developed distinctive sociotechnical understandings of the processes at play, through ad hoc combinations of science and technology studies (STS), sociology of organizations, political science, human geography and history.
