Purpose: In light of a largely negative discourse, this study aims to identify the various ways in which PhD mums have been supported in a range of contexts to develop a comprehensive typology of positive support, as well as to identify patterns that transcend institutional, national and disciplinary borders. Design/methodology/approach: The study is guided by ecological systems theory which allows for the investigation of the various interrelated systems that influence (in this case) doctoral researchers. A mixed-methods survey elicited the first-hand experiences from recent and current PhD mums across the world. Findings: The authors have identified a range of potential supports for PhD mums, but note a careful balance is needed to ensure that PhD mums are supported in their roles as both mother and doctoral researcher, where support in one domain does not contradict nor ignore support for the other. Originality/value: This study complements the existing knowledge body, which consists mainly of localised studies, by providing a birds-eye view of issues that transcend national, geographic and disciplinary borders. A topography provides a visual map of the various sources of potential support and the complicated relationships between them.
