This book offers a comprehensive, systematic presentation of the interdisciplinary research process and the theory that informs it by drawing on student and professional work from a variety of fields. Examples have been updated in the Fifth Edition so most are more contemporary, new content has been added on mixed methods and team research to respond to the needs of graduate students, and content has been revised throughout to address the current thinking on interdisciplinarity and integration, and strategies for achieving common ground as an interdisciplinary research team.
