André Ortega is a spatial demographer and urban geographer with research interests on spatial politics of peri-urban transformations, dispossession and gentrification, transnational migration, and critical demography. He is currently an assistant professor at the University of the Philippines Population Institute. He received his PhD in Geography at the University of Washington, Seattle in 2012. He currently heads the “Spaces in Transition? Mapping Manila’s Peri-Urban Fringe” project, a mixed-method research that accounts for multiple socio-spatial transformations in Manila’s peri-urban fringe, from multiple mobility patterns of residents to histories of various built environments. He has also been involved in a number of research projects across disciplines – particularly demography, geography, arts and humanities – with themes that discuss diverse issues, such as alternative economies of transnational migration, incongruity between landuse plans and community practices, and demography of Filipino youth.
