John Weinman is Professor of Psychology as applied to Medicines at the Institute of Pharmaceutical Sciences and Emeritus Professor at the Institute of Psychiatry, Psychology and Neuroscience in King’s College London. In his research he has investigated the influence of psychological processes on health, illness and health care delivery. He is particularly interested in the role of psychological factors in adaptation to and recovery from major illness and treatment, including surgery. A large part of this work is concerned with understanding the reasons underlying non-adherence to treatment, and in developing effective interventions for improving use of medicines and other recommended treatments. He has also taught undergraduate and postgraduate medical, pharmacy and psychology students, and is the author of a large number of books and papers in peer review journals.
