The Migration Research Hub supports the systematic accumulation of knowledge in migration studies. It aims to be the go-to resource for finding knowledge on migration, from the latest literature to the most appropriate topical experts. In the spirit of a collaborative approach to knowledge management in migration studies, researchers from all around the world are invited to contribute with their publications and expertise to further innovation in the field. The taxonomy of migration studies developed through this project allows everyone to identify opportunities for collaboration and new research projects across disciplines and geographies. The systematic approach to data collection and knowledge accumulation promotes and facilitates dialogue between researchers and policy stakeholders, and raises awareness of the latest debates and the most current and emerging questions about migration. The Migration Research hub was built during the IMISCOE-led Horizon 2020 project, CrossMigration (2018-2020). See a list of the team members below. The project is now fully integrated into and maintained by IMISCOE.
