Francesco Careri is an architect and a co-founder of Stalker/Osservatorio Nomade, an artistic and nomadic research group which, in 1995, started a series of walks in Rome and in various other European and American cities, exploring the system of interstitial voids of the urban archipelagos. He is Associate Professor in the Department of Architecture at Roma Tre University, where he experiences an itinerant approach to teaching through the Civic Arts laboratory, an entirely peripatetic-structure course which is organized through walking, getting lost, wasting time, and interacting in situ with the emerging phenomena of neglected urban spaces. Actually, he works on the living conditions of the Roma in Italy and Europe, as well as the hospitality of migrnats and refugees. He is the director of the Master Studi del Territorio/Environmental Humanities, and his main publications are the books Constant. New Babylon, una Citt Nomade, Testo & Immagine, Torino 2001; Pasear, detenerse, Gustavo Gili, Barcelona 2016, Sao Paulo 2017, and with Lorenzo Romito, Stalker/Campus Rom, Altrimedia edizioni, Matera 2017.
