Cathryn Costello is full professor of global refugee and migration law at the Sutherland School of Law at University College Dublin. She formerly held professorships at the Hertie School, Berlin (2010-2013), and the Refugee Studies Centre, University of Oxford (2013-2013). She researches international refugee and migration law and the multiple inclusions, exclusions and rights stratifications and violations they engender.

She currently leads the ‘RefMig’ project on mobility, status and rights in the global refugee and migration regimes and the ‘AFAR’ project on automated decision-making in migration and asylum governance.

She co-edited, with Megan Bradley and Angela Sherwod, IOM Unbound:  The Obligations and Accountability of the International Organization for Migration in an Era of Expansion; and (with Michelle Foster and Jane McAdam) The Oxford Handbook of International Refugee Law.

Her monograph on the Human Rights of Migrants and Refugees in European Law was co-awarded the 2016 Odysseus Academic Prize for ‘outstanding academic research in the area of European Immigration or Asylum Law’.  As well as international refugee and migration law, she also studies the intersection of migration and labour law. She is co-editor (with Mark Freedland) of Migrants at Work:  Immigration and Vulnerability in Labour Law.
