Dr. McGrath works to expand the work of Dalhousie University's Pediatric Pain Research Lab in areas including: delivery of care by distance treatment, the use of brain waves for pain measurement and the measurement and control of pain in cognitively impaired children and infants. The work involves two main research themes: the efficient and effective delivery of services to treat pain and other problems and the development of better measures of pain. His research will result in more accessible, effective and cost-efficient pain management for children.
