The ebook edition of this title is Open Access and freely available to read online. This edited collection brings academics, researchers and practitioners/public from a range of subject and discipline areas together with a view to providing insight into critical concerns and innovative practices on the process of developing and delivering Public Involvement and Community Engagement (PICE work) in a range of research settings. Delivering powerful reflections and insights from professional groups, marginalised communities and people with lived experience as research partners/participants each chapter will present from “real life” illustrative practice examples and each will engage in a sympathetic critical appraisal of a concern or innovation. Chapters will also provide methodological, theoretical and practice insight into the process of PICE work and each will explore the implications and lessons that can be learned in and across different subject and discipline areas. It is important to recognize here that this is a collection of work that will call for intuitive and informed professional practice that creates space for individuals to reflect on their own practice (involvement) and how they consider, conceptualise, learn, manoeuvre, and position themselves in relation to “doing PICE work”. Bridging a lack of knowledge and concern about the more critical and innovative aspects of PICE work in relation to representation, epistemic injustice, positionality, ethically informed and sustainable practice, this is pioneering reading for those who are interested in or concerned with the ever-pertinent issue of public involvement and community engagement in applied research practice.
