I study digital health: investigating how information and communication technology can be used to improve health and health services. I also have an interest in knowledge management and systems improvement in the NHS.

My work sits on the interface between research, policy and practice. My projects are usually interdisciplinary and collaborative, and are in three main areas: (1) Evaluating the effectiveness of ehealth tools - for example: three randomised controlled trials (the EXPERT study) of harnessing 'other people's experiences' as online health interventions; a randomised trial of an internet-based intervention on the NHS website to promote mental wellbeing in the general population; a randomised trial of an internet intervention for cardiac rehabilitation; the development of a serious game intervention for childhood obesity and the development and piloting of a virtual reality tool for the treatment of social phobia. (2) Studying the social aspects of connected health - investigating how a connected health world is changing how patients and the public interact with services and manage their own health. For example: a study examining the sharing of online patient experiences; a programme of work on internet reviews and ratings; and a study examining how young people are engaging with health care in new ways. (3) Investigating how the health service makes decisions - for example a study of how NHS commissioning decisions are made; and an ethnographic study of how NHS Chief Executives make decisions – both with Warwick Business School.
