His research focused on theories of spatial scales, urban studies, and discourse analysis, and he wrote a thesis on the role of major events in the internationalisation of Mediterranean cities. The thesis focused on the case studies of Valencia and Trieste and their respective narrative building around their supposed central location within the European and the Mediterranean space. During his Ph.D Giuseppe Porcaro had study periods at the University of Montpellier P. Valery, in Trieste, Valencia, Marseille, attended research workshops at the University of Newcastle upon Tyne, Bergamo, and assisted teaching to students at University of Naples, “L’Orientale”, and held a course in political geography for Masters’ students at the University of Basilicata. Part of the results of his research have been published in the chapter "Re-scaling Trieste: (not so) invisible networks, (dis)trust and the imaginary landscapes of the Expo 2008," co-written with Claudio Minca and included in the book Social Capital and Urban Networks of Trust. This is the first book on social capital and trust informed by a critical geographical perspective. The authors examine the role of social capital in the constitution and reproduction of urban networks of trust in different places and contexts. They explore how social capital and trust are reflected in the capacity of these networks to achieve their goals and to deliver specific forms of urban development in several Finnish and Italian cities. Giuseppe Porcaro has more recently worked on how the intersection between technology and politics is moving towards uncharted territories in the future. He has recently published a series of scientific articles about how the internet of things and algorithms will change policymaking.
