Tim Thornton's research concerns conceptual issues at the heart of mental health care. The philosophy of mental health and psychiatry is a rapidly developing area of collaboration by philosophers, clinicians (e.g. psychiatrists and mental health nurses) and mental health service users. Tim is a widely published international expert in this expanding field. He supervises PhD students in this and related areas of mental health and, with Gloria Ayob, he runs a Philosophy and Mental Health distance learning graduate programme at the University of Central Lancashire.
