This article focuses on the representation among the first class of graduates from a doctoral program in gerontology with respect to the interdisciplinary component within their curriculum. This component is presented as a source of personal and professional enrichment for students, and is essential to the deep understanding of complex phenomena that emerge in the aging process, and to the formation of a gerontological perspective. The fundamental condition for this favourable effect appears to be the establishment – in the context of seminars – of an inter-epistemological educational space that managed to extend itself to other areas of learning.
