Cross-disciplinary collaboration is being promoted in academic and professional circles as an important strategy for developing new avenues of scholarly inquiry and for generating knowledge that is immediately applicable to the resolution of real-world problems. This move toward cross-disciplinary work has translated into calls for enhanced interdisciplinarity in doctoral education, although there are several barriers to the successful implementation of cross-disciplinary work, especially during PhD studies. This article presents a personal narrative analysis of the authors' experiences in a doctoral-level transdisciplinary learning environment to illustrate the antecedents of successful cross-disciplinary engagement and the supports required to sustain this type of work.
