Santiago Orrego

studied Journalism (BA) and Sociology (MA) at Universidad de Antioquia, Colombia. He was working as a researcher at the same institution, leading an undergraduate group of research on urban and spatial studies. His master thesis, a study of case about the spatial transformation of Williamsburg, NYC, between the end of the 1980s and 2005, discussed the mainstream way of explaining the contemporary urban transformations, resulting in a discursive approval surrounding the concept of gentrification. He is currently working on the public nature of Times Square, regarding the controversy about the meaning of "the public" concept, mapped around the recent debates about the use and configurations of the pedestrian plazas in the area.
