I am Director of the Medical Care Research Unit which focuses on the development and evaluation of complex interventions for chronic conditions (telehealth for depression and CVD risk, adherence to nebuliser treatment for adults with cystic fibrosis). I also lead projects in emergency and urgent care (variation in avoidable emergency admissions, variation in ambulance non-conveyance). I have written extensively on methodology (how best to undertake mixed methods research, focusing more recently on qualitative methods with randomised controlled trials). I am currently studying how researchers develop interventions.

Research interests

Mixed methods, evaluation of new health services, patient views of health care, using qualitative research with RCTs, developing complex interventions.
