Dr. Longmuir is a Senior Scientist in the Healthy Active Living and Obesity Research Group at the Children’s Hospital of Eastern Ontario Research Institute.  Dr. Longmuir’s research interests are the promotion of physical activity to children with medical conditions and disabilities, and the use of physical activity to prevent and/or treat morbidity. Her undergraduate, Masters and Ph.D. theses examined the impact of interventions to increase physical activity among children with heart defects or cystic fibrosis. Dr. Longmuir’s post-doctoral fellowship was a community health promotion initiative targeting parents of young children. Dr. Longmuir has published more than 70 papers and 6 book chapters in the peer-reviewed literature. She has delivered over 180 scholarly conference presentations, and more than 80 invited and keynote addresses.
