Denis Kierans Researcher, The Migration Observatory and Global Exchange on Migration and Diversity

Denis Kierans is a Researcher at the University of Oxford’s Centre on Migration, Policy and Society (COMPAS). His work spans two COMPAS initiatives, the Migration Observatory and the Global Exchange on Migration and Diversity. This includes the facilitation of Inclusive Cities – a UK-wide network of 12 cities working on integration– and regular analysis and communication of migration and integration data for policy. He is a part of the 17 partner consortium leading the Measuring Irregular Migration and Related Policies (MIrreM) project.

Previously, he was a Data and Research Officer at IOM’s Global Migration Data Analysis Centre in Berlin. In this role, he co-authored the Guidelines for the Harmonization of Migration Data Management in the ECOWAS Region, which was disseminated across West Africa and is helping to lay the groundwork for improved production and sharing of migration data in the region and beyond.

Denis holds a Master’s degree from the University of Toronto’s Munk School of Global Affairs, where he focused on the movements of vulnerable groups within and between the EU and Russia.
