Lorna joined King's College London as Professor of Palliative Care and Child Health in November 2022. Her background is in clinical paediatrics and her research focuses on children and young people. She was the founding director of the highly successful Martin House Research Centre, a multi-disciplinary centre for research on the care and support of children and young people with life-limiting conditions, their families and the workforce that care for them. She has a portfolio of funding from the major funders, including two NIHR fellowships. Her main area of expertise is the use of routine data to influence policy and address healthcare inequalities. Her work has influenced national service specifications, children's palliative care funding, and vaccine prioritisation for children with COVID-19.

Working closely with children and their parents is central to her research and they were recently awarded the Royal College of Paediatric and Child Health Patient and Public Involvement prize. In 2018, Lorna was awarded the postdoctoral researcher award by the European Association of Palliative Care.
