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.
Mixed methods, evaluation of new health services, patient views of health care, using qualitative research with RCTs, developing complex interventions.
I run mixed methods workshops and clinics for PhD candidates and teach qualitative research with RCTs. I was Chair of the ScHARR Postgraduate Research Committee 2008-2012.
Panel Member of NIHR Applied Research Programme Grants 2007-2017
Deputy Chair of MRC Population Health Science Fellowships Panel 2010-2014
Associate Editor of Journal of Mixed Methods Research 2007-2012
