Research and scholarship

Current Projects 

  • GSES - An international collaboration aimed to create a standardised measure of child development for 0-3 year-olds. 
  • INDIGO - An international collaboration aimed to create a measurement tool to diagnose neurodevelopment delay in young children. 
  • MSK-Tracker - A trial involving the development and roll out of a tool to help patients and clinicians focus the content of their phsyiotherapy consultations based on the MSK-HQ PROM. 
  • TAPS - A validation project looking at the responsiveness to site specific pain of the MSK-HQ PROM. 
  • VESCA - An examination of methods to adjust the OSCE scores of medical students based on videos of performances. 
  • CLCF - The creation and preliminary validation of a tool to measure caregiver challenge in families of children with cystic fibrosis. 

Teaching

Gareth is currently contributing to the consturction and examination of the following courses;
