Profile

I am Director of the Health and Care Research Unit which focuses on the development and evaluation of complex interventions and services in healthcare, social care and third sector organisations. I have helped to develop interventions and evaluate them, leading the qualitative research and process evaluations. I also use mixed methods to understand service users' experiences of care. I am currently leading a project to help men in surveillance for abdominal aortic aneurysms to manage anxiety and exit surveillance when appropriate. I have written extensively on methodology (how best to undertake mixed methods research, focusing more recently on qualitative methods with randomised controlled trials, and how to develop complex interventions).
