Darcy D. Marciniuk, MD, FRCPC, FCAHS, Master FCCP is a Professor of Respirology, Critical Care and Sleep Medicine, and Associate Vice-President Research at the University of Saskatchewan, Saskatoon, SK, Canada.  Dr. Marciniuk is also the Medical Director of the LiveWell COPD Chronic Disease Management Program in the Saskatchewan Health Authority.

Dr. Marciniuk received his Doctor of Medicine from the University of Saskatchewan in 1984 and underwent specialty training in internal medicine and respiratory medicine at the University of Western Ontario and at the University of Manitoba.  He undertook research training at the University of Manitoba under the mentorship of Drs. Magdy Younes and Steven Mink.  Upon completing his research training, Dr. Marciniuk returned to Saskatoon where he assumed his current faculty position with the University of Saskatchewan.

Dr. Marciniuk is recognized internationally as an expert and leader in clinical exercise physiology, Chronic Obstructive Pulmonary Disease (COPD), and pulmonary rehabilitation with more than 420 invited international presentations and 200 peer-reviewed publications, chapters, and reviews (Google Scholar h-index 51).  Dr. Marciniuk is a past-President of CHEST (2012-2013) and the Canadian Thoracic Society (CTS) (2006-2007) and past-Chair of the Forum of International Respiratory Societies.  He served as a founding Steering Committee member of Canada’s National Lung Health Framework (2007-2011), and member and Chair of the Royal College of Physicians and Surgeons of Canada Respirology Examination Board (1999-2007).  Dr. Marciniuk was the lead author of three COPD clinical practice guidelines published by the CTS, a panel member of international clinical practice guidelines in COPD (ACP/ACCP/ATS/ERS), cardiopulmonary exercise testing (ATS/ACCP), pulmonary rehabilitation (ATS/ERS), and prevention of acute exacerbations of COPD (CTS/CHEST), as well as many clinical practice guidelines for the management of COPD published by the CTS. 

Dr. Marciniuk Co-Chaired the 2016 CHEST World Congress in Shanghai, China, and the American College of Chest Physicians International Conference in 2005.  He Co-Chaired the China-Chest Pulmonary Critical Care Medicine (PCCM) Steering Committee, where his efforts were instrumental in having the Chinese National Health and Family Planning Commission officially endorse PCCM as a pilot medical subspecialty in China in December 2016.

As Associate Vice-President Research, he led the development of the University of Saskatchewan’s International Blueprint and currently chairs the institution’s Pandemic Response and Recovery Team.  Dr. Marciniuk is a Fellow of the Canadian Academy of Health Sciences, and Deputy Editor (Outreach) for the journal CHEST.  He has been bestowed with the Distinguished Scientist Honor Lecture (2011) and the Thomas L. Petty Master FCCP Memorial Honor Lecture (2015) by the American College of Chest Physicians, the Founder’s Award (2013) by the Canadian Lung Association, the Christie Memorial Lecture and Award (2016) by the Canadian Thoracic Society, and the Distinguished Researcher Award (2013) by the College of Medicine, University of Saskatchewan.
