Brief Biography

Dr. Sharon Dell is a Pediatric Respirologist and Senior Associate Scientist at the Hospital for Sick Children and Associate Professor in the Department of Pediatrics and the Institute  of Health Policy Management & Evaluation at the University of Toronto. Her main clinical and research interests are in childhood airways diseases. Dr. Dell’s research program focuses on  respiratory epidemiology and outcomes. She is currently conducting several studies examining modifiable risk factors and diagnostic tests in childhood asthma,, as well as  multi-center studies evaluating phenotype/genotype correlations and outcomes in children with primary ciliary dyskinesia.   Her research is funded by the OLA, Health Canada, CIHR, and the NIH.  Dr. Dell is the Director of the Clinical Epidemiology & Health Services Research program at the University of Toronto where she is active in teaching and supervising graduate students. She is also a member of the Ontario Thoracic Society (OTS)  and Canadian Thoracic Society (CTS), and volunteers on many committees including the OLA’s Provider Education Program, the OTS Executive, and the CTS Asthma Clinical Assembly expert panel.  

Clinical Care Activities 

  • Asthma
  • Primary Ciliary Dyskinesia (non-CF bronchiectasis)
  • Interstitial Lung Disease

Research Interests

My main research interest is in the epidemiology of children’s airways diseases. Combining clinical epidemiology training with classical population-based observational epidemiology and health services research methods has enabled me to study a number of clinically relevant issues in childhood asthma, primary ciliary dyskinesia (PCD) and interstitial lung disease. I am particularly interested in identifying modifiable risk factors for childhood asthma. This has led me to my current main research program which is investigating the effects of traffic-related air pollutants (TRAP) on childhood asthma in Toronto school children. I am also a principal investigator in a multi-center clinical studies of children with PCD and interstitial lung disease.
