Background:

David Clark was an undergraduate at Lincoln College from 1974 – 77, where he studied Chemistry before switching to Experimental Psychology. He subsequently trained as a clinical psychologist at the Institute of Psychiatry (Kings College London) and completed his DPhil at Wolfson College in 1983. His first academic appointment was as a university lecturer and then Professor in the Oxford Department of Psychiatry. From 2000 – 2011 he held the Chair of Psychology at the Institute of Psychiatry, Kings College London. He is currently the Chair of Experimental Psychology in Oxford and NHS England’s National Clinical and Informatics Advisor for the Improving Access to Psychological Therapies (IAPT) programme.

Teaching:

David Clark runs an undergraduate advanced option series of lectures and tutorials on ‘Developing New Psychological Treatments’ and also contributes to lectures for medical students and the MSc in psychological research. He conducts masterclasses in cognitive therapy for the Oxford Doctorate in Clinical Psychology Programme and supervises graduate students.

Research interests:

He is well-known for his work on the understanding and treatment of anxiety disorders. With colleagues, he has developed original and effective cognitive-behaviour therapy programmes for four different anxiety disorders: panic disorder, social anxiety disorder, post-traumatic stress disorder and health anxiety (hypochondriasis). More recently, his team have developed internet based versions of the social anxiety and PTSD treatments. David has also played a key role in large-scale initiatives that aim to make evidence-based psychological treatments more widely available to the public. The first initiative involved training local clinicians to treat post-traumatic stress disorder following the 1998 car bomb in Omagh, Northern Ireland. The second is the Improving Access to Psychological Therapies (IAPT) programme, which aims to vastly increase the availability of psychological therapies for depression and anxiety disorders. David Clark is one of the principle architects of this programme which currently treats over 500,000 people a year, collects outcome data on 98% and places this information in the public domain in order to promote transparency about mental health outcomes.
