- Overview
-
My research is focused on how exercise affects children with heart disease and other childhood diseases. Specifically, our group studies how exercise affects health outcomes, how it can be used as a tool to treat patients, and how behavioural change strategies are needed to help patients make changes to their exercise habits. I am also involved in work that looks at the use of digital health tools to deliver exercise programs, change behaviours and provide more comprehensive care for patients and their families. Finally, our group is involved at looking at the environmental impact and costs associated with travel to BCCH.

Virtual Reality and Gameplay as a Model for Exercise Rehabilitation in Pediatric Solid Organ Transplant Patients
Building on previous work that delivered a virtual exercise program to children with a solid organ transplant, this study looks at whether virtual reality gameplay yields a sufficient training stimulus to mimic traditional exercise.Complementing Care in Cardiology: The use of mobile health technology to support patients and families in the Children’s Heart Centre
This study builds on initial work in our solid organ transplant and adolescent dysautonomia populations where a clinical digital messaging platform was employed to try to improve communication and in turn quality of life in these patients. Now, we have expanded the use of the clinical digital messaging platform to include a widespread group of patients seen in the Children’s Heart Centre.Is exercise capacity related to sports participation in children with congenital heart disease?
This study aims to evaluate how sports participation affects exercise capacity in children with congenital heart disease. The goal of this work is to elucidate the factors that may influence exercise capacity in these children.GrantsTransplant Research Foundation of BC Venture Grant and CDTRP Venture Grant (2022) - Virtual Reality and Gameplay as a Model for Exercise Rehabilitation in Pediatric Solid Organ Transplant Patients.
