Yvonne Jewkes is Professor of Criminology at the University of Bath and Honorary Visiting Professor at the University of Melbourne. She has been carrying out prison research—much of it ethnography—for over 20 years and has spent the last decade researching and writing about prison architecture and design and their potential to rehabilitate. She has recently held two Economic and Social Research Council grants to study these topics and has worked as a consultant to prison architects and senior prison service personnel around the world. She has published extensively on various aspects of prisons and imprisonment, including (with Ben Crewe and Jamie Bennett) The Handbook on Prisons (2nd ed., 2016, Routledge). With Ben Crewe and Thomas Ugelvik, she is the Founding Editor of the new SAGE journal Incarceration.     Gayle Letherby is an honorary professor of sociology at the University of Plymouth and a visiting professor at the University of Greenwich. Alongside substantive interests in reproductive and non/parental identities; gender, health, and well-being; loss and bereavement; travel and transport mobility and working; and gender and identity within institutions (including universities and prisons), she has an international reputation in research methodology. Expertise in this area includes feminist and qualitative approaches and in auto/biography and creative reflexivity (with reference to data collection and presentation). Gayle is currently a coeditor of the SAGE journal Methodological Innovations and is in the process of editing the Handbook of Feminist Research for Routledge. In addition to her own research and writing, Gayle has significant experience in research mentoring and consultancy both within academia, for grant funding bodies and for HealthWatch UK.
