Carers in academia is a young but growing field, which has quickly expanded since the 2000s and has gained new momentum during the Covid-19 pandemic and the accompanying disruptions of personal and professional lives. It is also one which, through its associations with reproductive and women's work, remains relatively marginalised. This article examines the English language research literature on carers in academia. Drawing upon feminist poststructuralist theories, we contend that, because the literature is not 'out of the discourses' of care and academic work and, instead, contributes to construct the objects it speaks of, the state of the field is a matter of cognitive and social justice. Following the presentation of the methodological and theoretical frameworks and a discussion of the authorial voices framing the field, we consider the relative in/visibilities of various groups of care/rs. Drawing on a review which identified 158 relevant texts, we find research in the field broadly ignores male, disabled, BME and LGBTQ+ carers, as well as ancillary workers and professional groups other than academics, and forms of care work other than parenting healthy, abled children. We then move to discussing the liminalities of care, noting the absence of studies of care work in academia related to non-humans and to end of life. We conclude by pointing out the need for further reflexivity in terms of how processes of knowledge production include and exclude in ways that are complex and fluid.
