Azadeh Yadollahi is an emerging investigator in the field of sleep and airway disorders. In 2014, she was appointed a Scientist at TRI—one of five research institutes within UHN—and recently obtained an academic appointment as Assistant Professor at the prestigious Institute of Biomaterials and Biomedical Engineering at the University of Toronto. She is also an Adjunct Faculty Member in the Graduate Department of Biomedical Engineering at the University of Manitoba. 

Dr. Yadollahi completed her doctoral training with Dr. Zahra Moussavi, Canada Research Chair in Biomedical Engineering and Director of the Graduate Program in Biomedical Engineering at the University of Manitoba, where she developed expertise in analyzing respiratory sounds and their application for diagnosing sleep apnea. As a visiting scholar at the Harvard University School of Public Health, she received asthma training from Dr. Jeffrey Fredberg, Professor of Physiology and world expert in mechanisms of airway narrowing in asthma. She then pursued postdoctoral training under renowned respirologist Dr. T. Douglas Bradley, Medical Director of the Centre for Sleep Health and Research at UHN, Director of the Respirology Program at the University of Toronto and the Clifford Nordal Chair in Sleep Apnea and Rehabilitation Research. Here, she honed her skills and developed an expansive repertoire of techniques with which to study the effect of the recumbent position during sleep on the severity of sleep apnea.
My research program is dedicated to understanding the intricate interplay between sleep, body fluid shifts and respiratory diseases. Our goal is to develop innovative technologies for the long-term monitoring of physiological signals during sleep, with the ultimate goal to improve management of chronic respiratory disorders during sleep.
As part of the Sleep Science Team at the Toronto Rehabilitation Institute, our research will lead to a better understanding of the pathophysiology of chronic respiratory disorders during sleep—improving disease management and enabling the development of commercializable products to benefit the millions of Canadians with chronic respiratory diseases.

Key research areas within my program include:
1- Chronic respiratory disorders including sleep apnea and nocturnal asthma
2- Physiological signal processing
3- Assessment of body composition
4- Medical devices for diagnosis and treatment of chronic respiratory disorders
5- Acoustics
