David M Clark studied Experimental Psychology at Oxford University (MA, DPhil) and was clinically trained at the Institute of Psychiatry (MPhil). His first academic appointment was as Lecturer in Clinical Psychology at Oxford University, where he subsequently became a Wellcome Trust Principal Research Fellow and a Professor of Psychiatry. He was also a Fellow of University College, Oxford. Since 2000, he has been Professor of Psychology at the Institute of Psychiatry, Kings College, London. He is also a Director of the Centre for Anxiety Disorders and Trauma at the Maudsley Hospital and (Honorary) Clinical and Research Advisor to the Northern Ireland Centre for Trauma and Transformation in Omagh. He is a Fellow of the British Academy (London), a Fellow of the Academy of Medical Sciences (London), an Honorary Fellow of the British Psychological Society, and Distinguished Founding Fellow of the Academy of Cognitive Therapy (USA). Other posts have included: Chair of the British Association of Behavioural and Cognitive Psychotherapies (1992); President of the International Association of Cognitive Psychotherapy (1992-95); Visiting Professor of Psychology and Psychiatry at the University of Pennsylvania (1991) and Fellow, Center for Advanced Study in the Behavioral Sciences, Stanford Univsersity, USA (2005). Honours and awards have included: the May Davidson Award (British Psychological Society), the American Psychological Association Distinguished Contribution to Applications of Psychology Award, the Academy of Cognitive Therapy’s Research Award, an Honorary Doctor of Science from the London School of Economics (LSE), being voted a World Leader in Anxiety Disorders Research by members of the Anxiety Disorders of America Association (1998), and the Behaviour Research and Therapy Award for the most outstanding article ( “A Cognitive Approach to Panic”) published in that journal in the first 30 years since its founding in 1962.

Activities and Interests

Professor Clark’s research focuses on cognitive approaches to the understanding and treatment of anxiety disorders. His research involves a closely integrated programme of experimental and clinical studies. The general strategy has been to: (i) use clinical interviews and cognitive psychology paradigms to identify the core cognitive abnormality in an anxiety disorder; (ii) to construct a theoretical account which explains why the cognitive abnormality does not self-correct; (ii) test the hypothesised maintaining factors in rigorous experimental studies; (iv) develop specialized cognitive treatments which aim to reverse the maintaining factors; (v) test the efficacy of the treatments in randomised controlled trials, and (vi) make the treatments more broadly available with dissemination studies. In collaboration with colleagues, the research has led to the development of new and effective cognitive therapy programmes for panic disorder, hypochondriasis, social phobia and posttraumatic stress disorder
