He subsequently worked with Barbara Starfield as a post-doctoral Research Fellow at the Department of Health Policy and Management, Johns Hopkins University, and then he went on to take a post as Clinical Lecturer at the National Primary Care Research and Development Centreand the NIHR School of Primary Care Research, University of Manchester.

His research is focussed on the routine use of Patient Reported Outcomes in clinical practice, the study of the implications of multimorbidity for the provision of health services, the evaluation of interventions aimed at quality improvement of health care and more generally research aimed at improving the delivery of primary health care. He has led the development of an integrated model of quality of life and other Patient Reported Outcomes , and has led the development of the Patient Reported Experiences and Outcomes of Safety in Primary Care .
