Moving People and Knowledge provides a fresh examination of the processes of highly skilled science migration. Focusing on intra-European mobility and, in particular, on the new dynamics of East–West migration, the authors investigate the movement of Polish and Bulgarian researchers to and from the UK and Germany. Key questions include: who is moving, how long for, and why? In addressing the motivations and experiences of mobile scientists and their families, insights into professional and personal motivations are provided, demonstrating how relationships, networks and infrastructures shape decision-making. This book provides a useful perspective on the implications of increasing researcher mobility – for both sending and receiving regions and the individuals concerned – which is necessary for the construction of future policies on sustainable scientific development.
