Biography
Thomas Lacroix is CNRS Director of research in geography. He works on the relationships between immigrant transnationalism and the state, with a focus on North African transnationalism. He extensively published on the migration and development relationship, diasporic memory, the moral geography of migration or the theory of transnationalism.
More recently, Lacroix’s research examines cities and city networks engagement on migration and integration issues. He is particularly interested in the place of cities in the building of a global migration governance framework. He also explores the epistemology of migration studies, with a special interest in the role of the Critique in migration research and the social engagement of scholars. He is engaged in a multidisciplinary dialogue between social scientists and other disciplinary domains such as the humanities, philosophy and mathematics.
