This chapter reflects on liminality, a guiding concept in the project that brought both authors to Edinburgh and has featured prominently in Graeme Laurie’s most recent work. It introduces the concept of liminality and discusses Laurie’s framing and use of the term before going on to illustrate how both the concept and Laurie’s approach to it have shaped and facilitated further research on the ethics and governance of reproduction. The chapter considers the wider implications of Laurie’s contributions to the field, drawing out some of the key themes of his work on liminality, namely the processual, the experiential and the ‘quality of in-between-ness’. It provides new perspectives by applying these themes to research on the ethics and regulation of surrogacy as well as artificial womb technology. The chapter argues for the relevance of liminality as an analytical framing device, to reveal important lessons for ethics and law beyond the realm of health research regulation. Finally, the opportunity is taken to reflect on Laurie’s guidance as a project leader and the ways in which the authors’ own liminal identities in the project laid the foundation for their future as researchers.
