I am Professor of Primary Care and Director of the Imperial Child Health Unit  at the School of Public Health, Imperial College London, the UK’s pre-eminent research group for primary care of children. I graduated in medicine from St Bartholomew's Medical College and trained in London. I have practised as a GP in London and led research focusing on the use of electronic health records from health and social care to improve children and young people's health and reduce health inequalities. I support academic capacity building as Chair of the NIHR Academy’s Selection Committee for Doctoral Research Fellowships. In 2023, I was awarded an NIHR Senior Investigator award.


I am the institutional (Imperial) lead for the national Children and Families Programme of the  National School for Public Health Research (SPHR) and Executive Board Member. I am a founding member of the SPHR Equality, Diversity and Inclusivity Committee. I provide cross school leadership as External Review Panel member for the National School for Primary Care Research. Locally, I lead the Child Population Health Theme for the NIHR Applied Research Collaboration in Northwest London that aims to improve the health of children and families.

In 2013, I led a successful application for a Silver Athena SWAN award for the School of Public Health to support career progression for women and disadvantaged staff and students. I have been academic mentor to numerous mentees as promotions champion at Imperial, university schemes across London, NIHR Academy Mentoring Programme and Oxford International Primary Care Research Leadership Programme.


I have been a practising GP in Putney, London since 1995. All of my research stems from encounters with patients and the public.
