Gareth is a psychologist primarily interested in developing and evaluating interventions to change health behaviour. As a researcher in the Behaviour and Health Research Unit, he is currently working on a range of evidence reviews and primary research projects examining the most effective ways to change behaviour at the population level (www.bhru.iph.cam.ac.uk).
Gareth studied Experimental Psychology at the University of Oxford, followed by clinical roles in the NHS (in neurological rehabilitation and in early intervention for psychosis). He then worked in HIV/AIDS research and counselling in San Francisco, USA, followed by an MSc in Health Psychology at University College London. He completed a PhD in Health Psychology at the Institute of Psychiatry, King’s College London, awarded in 2010, and joined the Behaviour and Health Research Unit in 2011.

- The effects of communicating highly salient risk information (e.g., aversive visual images, genetic risks) on behaviour, and underlying cognitive and emotional mechanisms;
