My research aims to provide evidence to improve child health and wellbeing in the population, and thereby reduce the population burden from poor health. I lead a team of researchers in the Child Health Unit with funding support from the National Institute of Health Research (NIHR) Programme Development Grants and fellowships and charities.
It has expanded to become one of the UKs leading research groups on primary care of children. Our methodological strengths include analysis of large routinely collected health and social care data sets and surveys, evidence synthesis, consensus methods for evaluation of practice and policy. Founding principles of my research are its relevance in addressing priorities for children and families, a multidisciplinary approach to the pursuit of knowledge and timely translation into practice and policy. I am also committed to building academic capacity in child health and primary care.
I co lead the 'Harnessing data to improve Children and Young People’s Health' for the National School for Public Health Research (SPHR). I have established several on going collaborations nationally and internationally with the Global Burden of Disease (GBD) Project and through my role as Vice President of the European Public Health Association’s (EUPHA), Child and Adolescent Section. I have continued clinical practice as an inner city GP in London since 1995. I also support research as Panel Member for NIHR Doctoral Fellowships, as member of the BMJ International Advisory Board. I also support early career researchers through 1 to 1 mentoring programmes such as the Oxford Initiative for Primary Care Research Leadership. I am also a practising GP in Putney.
1. Improving primary care quality for children
This NIHR funded work programme uses clinical electronic records to identify how to improve the management of chronic conditions diagnosed in childhood including asthma, diabetes and inflammatory bowel disease
2. Child obesity and early cardiovascular risk
This work stream explores ways of tackling excess weight in children. The PROMISE programme-( Paediatric Research in Obesity Multi-modal Intervention and Service Evaluation NIHR funded grant in collaboration with UCL/ LSHTM) enabled the largest evaluation of the UK National Childhood Measurement Programme (NCMP) in England and piloting of web based tools to help clinicians to assess growth and guide weight management in children. My US collaboration with Professor Arch Mainous III (University of Florida, U.S.) and Harvard University explores health system approaches to reduce disparities in cardiovascular disease
3. Reducing the burden of infectious illness in children
This theme examines how preventive primary care and antibiotic treatment impacts on infectious illness in children. Current themes are focused on exploring ways of optimising antibiotic prescribing in primary care by developing and validating prescribing rules.
