Brief Biography

Dr. Narang completed medical school and paediatric training in the U.K. She completed her respirology fellowship program at Great Ormond Street Hospital and the Royal Brompton Hospital in London, U.K. Following this, she undertook training in Sleep Medicine at the Children's Hospital of Philadelphia, U.S. Dr. Narang also completed a three-year research degree in paediatric pulmonology and was awarded her Doctor of Medicine (MD research) degree at the University of London. She was appointed as Faculty and the Director of Sleep Medicine at The Hospital for Sick Children (SickKids) in 2007.

Research Interests

Dr Narang’s ultimate research goal is to advance clinical care and reduce morbidity related to sleep disorders in both healthy children and children with underlying co-morbidities. Currentlym Dr. Narang’s research focuses on identifying children with obesity most at risk for obstructive sleep apnea (OSA) and their neurocognitive, metabolic, and cardiovascular outcomes. This research is being undertaken as part of the wider Canadian Sleep and Circadian Network (CSCN) funded by CIHR, for which Dr. Narang is the paediatric lead member (www.cscnweb.ca). Dr. Narang, along with Dr. Andrea Kassner, is also evaluating cerebrovascular injury and related adverse neurocognition using brain MRI in obese youth with OSA (funded by Heart and Stroke Foundation).

Ongoing Research Interests:

  • Understanding the interaction of sleep disorders with cardiovascular and metabolic morbidity, particularly in obese children with OSA
  • Evaluating the mechanisms that underlie neurocognitive dysfunction in children with OSAValidating portable monitoring devices for the diagnosis and management of OSA
  • Understanding the bidirectional relationship between sleep disorders and asthma
