Introduction
My research is focused on supportive care for children with cancer, and the interaction between socio-demographic determinants of health and malignancy. This includes: evaluating healthy active living for survivors of childhood cancer; provision of care for marginalized children, including Indigenous children in Canada and for all children in low-income countries; and how to harmonize Traditional and complementary medicines with conventional cancer care globally, in a safe and effective manner.
