Research Interests

Louisa's research portfolio is orientated around delivering responsive, practical research solutions that result in real world impact. Her previous research includes:
  • undertaking a number of weight management service evaluations which have informed practice development and commissioning decisions
  • undertaking two mixed method reviews of behaviour changes resulting from marketing and fiscal strategies targeted at high sugar products, that underpinned the PHE sugar reduction report: from evidence to action, and subsequent changes to marketing and fiscal regulation.
  • leading a series of Cochrane reviews examining treatment interventions for child and adolescent overweight and obesity which helped to inform ongoing work by the World Health Organization on the management of children and adolescents with overweight and obesity.
This is in addition to supporting a number of Public Health England outputs such as the Guide to Delivering and Commissioning Tier 2 Weight Management Services, the standard evaluation framework for weight management interventions, guidance on family weight management: changing behaviour techniques.

Current research projects include a programme of work to support the PHE diet, obesity and physical activity team; an evaluation of an innovative local tier 2 family weight management service, and three NIHR funded projects: BEhavioural Weight Management: COMponents of Effectiveness (BE:COME); Understanding the effectiveness and underlying mechanisms of lifestyle modification interventions in adults with learning disabilities; and Can embedding the MapMe intervention, a tool to improve parental acknowledgement and understanding of childhood overweight and obesity, in the National Child Measurement Programme lead to improved long term child weight outcomes at one year?.
