Researchers in applied linguistics have found medical and health contexts to be fertile grounds for study, from macro-levels of conceptual analyses to micro-levels of the "turn-by-turn." The rich array of health contexts include medical research itself, clinical encounters, medical education and training, caregivers and patients in everyday life - from the formal and ritualized to the ad hoc and ephemeral. This volume foregrounds the crucial role of applied linguists addressing real world problems, while simultaneously highlighting the varied ways that health can be understood as a rich site of language inquiry in its own right. Chapters cover a range of health topics including medical training, medical interaction, disability in education, health policy analysis and recommendations, multidisciplinary research teams, and medical ethics. While reporting and reflecting on their specific topics in clinical and health contexts, contributors also articulate their own hybrid identities as professional collaborators in health research, education, and policy.
