My research is aimed at finding better ways to prevent, detect and treat childhood illness. 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. I am also a practising GP in Putney

Research areas

1. Role of primary care in child health

I lead an NIHR funded work programme examining the role of primary care in improving health of children and young people. This work encompasses prevention of  infectious illness and chronic disease and how timely primary care can avoid hospital admission in children

2. Chronic diseases diagnosed in childhood

I lead several NIHR funded studies examining long term clinical outcomes in premature infants, and long term outcomes of chronic disease diagnosed in childhood including obesity, diabetes and inflammatory bowel disease

3. Child obesity and early cardiovascular risk

This research theme explores impact of ethnicity, obesity and early cardiovascular health on child health with funded studies including the Paediatric Research in Obesity Multi-modal Intervention and Service Evaluation  (NIHR funded programme development grant in collaboration with UCL/ LSHTM).
