Leo Lucassen is an internationally renowned researcher in the field of migration history. He studies the global migrations of the past millennium, interactions between migrants and existing populations, and migration policies. His research thus bridges the gap between historical research and the social sciences. He regularly engages in public debate, for example as a guest on the Dutch political interview programme Buitenhof, as a contributor to Dutch national newspapers, and as an active Tweeter. Lucassen and his brother Jan (honorary IISH fellow and Academy member) co-authored the book Vijf eeuwen migratie [Five centuries of migration] (2018).
