My research interests range from studies involving paediatric hip, lower limbs, feet, trauma and bone tumours. I am specifically interested in advancing research around paediatric bone health and mobility. In addition to looking at the clinical outcomes, I am also interested in looking at the outcomes reported directly by the patients or caregivers of patients, specifically their quality of life. By studying these outcomes, I am aiming to look at the effectiveness of treatments I use in clinic and to explore ways to improve the quality of life of my patients. I also collaborate with biomechanical engineers to generate computerised models of the hip in order to imitate different deformities around the hip joint.

Preventative Multimodal Analgesia for Children Undergoing Lower Limb Reconstruction with External Fixators: A Prospective Study of Postoperative Pain
Objective: To assess the peri-operative analgesia regimen that has been previously developed for children undergoing limb reconstruction surgery at BC Children’s Hospital, during the acute and long-term post-operative recovery phase. This study is being conducted in collaboration with the Department of Anesthesiology, Pharmacology & Therapeutics.

Multicentre Pin Site Infection Study
Objective: To measure and document pin site infection rate and pin site care across Canada, US and UK through a multi-centre pin site infection database. This study involving ten surgeons (BCCH being the primary site) across various sites will provide important information for limb lengthening and reconstruction services across the world, as well as parents/primary caregivers of children in external fixation devices (EFDs). By identifying the factors contributing to pin site infections, this study will take another step towards improving clinical care for children in EFDs.

Health-related Quality of Life in Children with Lower Limb Deficiency
Objectives: a) To develop and validate a patient-reported quality of life tool for children with lower limb deficiency; b) To establish the baseline health-related quality of life in these children using the newly developed tool; c) To investigate the quality of life of caregivers of children with lower limb deficiency.
