I am a political and population geographer specializing in research on human migration and migration governance, using both qualitative and quantitative methods. In addition to comparative work on diasporas and transnationalism, I publish and lecture internationally on topics such as migration and development, highly skilled migration, global migration governance, international migration data, and methodology in migration studies. I am a Research Associate at Oxford University attached to both the International Migration Institute and the Centre on Migration, Policy and Society, and a Senior Member at St Antony’s College. I lead the Diaspora Engagement Policies Project, part of the five-year Oxford Diasporas Programme, which is funded by a five-year Large Programme Grant from the Leverhulme Trust. I am also the Editor-in-Chief of Migration Studies, an academic journal published by Oxford University Press.
