David's primary research focuses on international migration. His current work explores the relationship between immigration and happiness, investigating whether (as many would assume) migration to a wealthy country is advantageous to the immigrants themselves in the sense that it brings them greater happiness. Articles emerging from this research have been published in Migration Studies, Social Indicators Research, Journal of Happiness Studies, and International Studies Review, among others. He has done consulting work on this topic for the International Organization for Migration in Geneva. He has also held a grant from the Economic and Social Research Council to investigate the UK "citizenship process".
David is currently Senior Lecturer in Sociology at the University of Leicester. He gained a PhD from the University of Wisconsin-Madison and a BA from Kenyon College. He is also on the board of RC31, the International Sociological Association's section on the sociology of migration.

"Demonstrates that the study of international migration has really come of age. From acculturation to undocumented immigration, the authors consider more than three dozen concepts at the heart of migration studies. Clearly written in a highly readable style, the book is a valuable resource for students and scholars alike."
- Nancy Foner, City University of New York
"This very useful and authoritative compendium explicates thirty-eight concepts central to analysis of international migration. It is accessible to undergraduate students and even can enrich graduate courses. It nicely complements books like The Age of Migration or Exceptional People. Concision is a virtue!"
- Mark J. Miller, University of Delaware
This book provides lucid and intuitive explanations of the most important migration concepts as used in classrooms, among policymakers, and in popular and academic discourse. Arguing that there is a clear need for a better public understanding of migration, it sets out to clarify the field by exploring relevant concepts in a direct and engaging way. Each concept:

• Includes an easy to understand definition


• Provides real-world examples


• Gives suggestions for further reading


• Is carefully cross-referenced to other related concepts
