Immediately after its appearance, we at the University of Amsterdam's Institute of Interdisciplinary Studies enthusiastically adopted Allen Repko's "Interdisciplinary Research: Process and Theory" (Repko, 2008) as it was the first textbook that offered systematic explanation of and guidance through the complexities of an interdisciplinary research project. However, several characteristics of the projects conducted by our students made it an uneasy match for their needs and ours. For one thing, the Repko text targets students doing individual research projects whereas our students typically perform interdisciplinary research in teams. Our students also typically bring more disciplinary expertise to their interdisciplinary work than those whom the Repko text targets. And they often undertake empirical research as part of their projects--and not just the research in relevant literature that is emphasized in the Repko texts. Feeling the need for a textbook on interdisciplinary research that would better support students like ours, we decided to develop our own textbook, "Introduction to Interdisciplinary Research: Theory and Practice." In this article, we describe the version of the research process we present in our text, emphasizing the many forms of pluralism involved in the process as reconceived to better suit teams of researchers based in different disciplines, and sometimes pursuing empirical work which may involve extra-academic stakeholders.
