Pain in Child HealthPain in Child HealthA Cross-Canada Research Training ConsortiumA Cross-Canada Research Training Consortium
Principal Investigators:
Patrick McGrath, Ken Craig, Allen Finley, Celeste Johnston, Bonnie Stevens, Carl von Baeyer
Research mentors:
Over 30 active researchers in five centers with a shared focus on pediatric pain
Goal:
To develop a community of scholars in pediatric pain
Activities for Trainees in Pain in Child Health:
• Visits to other labs • Web based courses on pain• Annual summer/fall institute • International speakers series
• Supplementary funding for support of trainees • National lab meeting by means of web distance tools
Trainee membership in the consortium is open to people with a commitment to the study of pain in child health in Canada, in any discipline and at any level in their training.
Membership makes trainees eligible for (but does not guarantee) financial assistance. The major training centres are Halifax, Montreal, Toronto, Saskatoon and Vancouver.
