Giulietta Laki (ULB - Grap, Faculty of Social Sciences and Philosophy; sASHa, Faculty of Architecture) is a German anthropologist researching and working on cities and diversity with a strong focus on innovative and experimental methods, both from the arts and from social sciences. Her research activities cross academic borders through interdisciplinary collaborations and research missions (Mudam Luxembourg, Fabrik Saint-Josse), by giving workshops (a.pass, Human Cities Festival, Académie des Beaux Arts de Bruxelles) or curating urban interventions (Maelström festival outdoors 2011, Maelbeek Dans Tous Ses Etats EGEB). She is a member of P3G, combining collective readings of pragmatist literature with inquiries in Anthropology & STS. In 2018 she completed her PhD thesis entitled “Streets, things and their publics. An ambulatory exploration of Brussels objectal public space”, which presents an empiric and ethnographic approach to the public sphere, attesting that objects in urban environments have a political agency and enable what she calls an “objectal participation” to public life.
