Soledad Álvarez-Velasco is a Junior Professor of "Migration and the Americas" at the Heidelberg Center for Ibero-American Studies at University of Heidelberg. She holds a PhD in human geography from King's College London. Her research analyses the interrelationship between mobility, control, and spatial transformations across the Americas. She focuses on the intersection between undocumented south-north transit migration, border control regimes, the formation of migratory corridors across the Americas and the migrant struggle across these transnational spaces. She also studies the irregularized movement of unaccompanied migrant children who transit through the extended corridor connecting South America with Mexico and the United States, as well as the transnational smuggling networks operating across it. She is a member of the Colectiva Infancias and Colectivo de Geografía Crítica del Ecuador.
