Karen has been researching migration, mainly using ethnographic methods, since the early 1990s. Starting with British emigration to Spain, she wrote the British on the Costa del Sol in 2000 (Routledge). She then spent several years establishing the field of lifestyle migration, and is especially known for the edited volume Lifestyle Migration: relations experiences and expectations (Ashgate 2009, ed with M. Benson). Later she has focused on employing sociological theory for broader understandings of migration processes. This work has been published in international Migration and Social Theory, (Palgrave 2012), and Lifestyle Migration and Colonial traces in Malaysia and Panama (Palgrave 2018, with M. Benson).
Karen’s main contribution to migration studies has been to advocate the telling of practice stories to elucidate the structural and agentic aspects of migration processes and how these interrelate over time. This has informed much of her work, including the recently published International Labour migration to Europe’s Rural Regions (Routledge 2021, ed with J.F. Rye).
