Biography

Dr. Vozoris is an Assistant Professor and Clinician Investigator within the Division of Respirology, Department of Medicine, at the University of Toronto. He is also a Staff Respirologist at St. Michael’s Hospital with expertise in sleep medicine, hereditary hemorrhagic telangiectasia (HHT) and tuberculosis. He completed a Masters of Health Sciences degree in the Department of Community Health at the University of Toronto prior to his medical training. He also undertook research training at the Institute of Clinical Evaluative Sciences prior to coming on faculty at the University of Toronto. His main research interest is areas of overlap between sleep medicine and obstructive lung disease, such as the pharmacoepidemiology and health outcomes of sedative medication use in chronic respiratory disease populations. He also has research interests in the health effects of insomnia.  He uses observational study designs and techniques, and different types of pre-existing, population-based databases, such as Ontario provincial health administrative databases that are housed at the Institute of Clinical Evaluative Sciences and United States national health survey data that are available through the Centers for Disease Control and Prevention. He is a member of the Ontario COPD Population Health Network (COPD OPHN), which is a group of academic respirologists from various universities across Ontario who are working collaboratively on health services and health outcomes research relating to COPD.
