Peter Cooper is emeritus professor of psychology at the University of Reading. His academic research has focused on two main areas: the nature and treatment of disorders of eating; and the impact of psychological problems on parenting and child development. In recent years he has directed most of his professional attention to ways of supporting parents living in conditions of adversity - especially in parts of Africa - as a means of improving child developmental outcomes. For ten years, while a lecturer at the University of Cambridge, he ran an NHS clinic for people with bulimia nervosa. Arising from this experience he wrote a book - essentially a self-help manual - entitled Overcoming Binge-eating and Bulimia Nervosa. The current book is an edited update of this original work. In 2016, in recognition of his contribution to academic and professional psychology, he was made a fellow of the British Academy.
