Paul Fletcher is Bernard Wolfe Professor of Health Neuroscience at the University of Cambridge. He is an internationally recognised leader in cognitive neuroscience and functional neuroimaging of psychiatric and other behavioural disorders. His work is strongly interdisciplinary and distinctive for its depth and sophistication in the cognitive analysis of symptom formation. Fletcher has been able to translate cognitive neuroscience to metabolic medicine, as well as psychiatry, thus pioneering the new field of health neuroscience and contributing to a deeper, neuroscientific understanding of the maladaptive behaviours that often contribute to risk for somatic disorders.
