Clinical Focus

Dr. Kay graduated in medicine from the University of Birmingham in the United Kingdom in 1960 and trained in pathology at the Universities of Bristol and Birmingham. He became interested in pulmonary pathology and pulmonary vascular disease while working with Dr. Donald Heath at the Universities of Birmingham and Liverpool, and Dr. Robert Grover at the Cardiovascular Pulmonary Research Laboratory in the University of Colorado Medical Center, Denver, Colorado. Dr. Kay has been a member of the Faculty of Health Sciences at McMaster University since 1977 where he is currently Professor Emeritus in the Department of Pathology and Molecular Medicine. He has authored or co-authored over 100 peer-reviewed papers, book chapters and review articles relating to his clinical and research interests in pulmonary pathology, pulmonary vascular disease and drug-induced lung disease.
