Dr. Johnson is a Scientist at SickKids Research Institute. He received his Bachelor of Biomedical and Electrical Engineering at McMaster University and successfully read for a DPhil at the University of Oxford. Dr. Johnson has worked in machine learning and health care for over a decade. Throughout his career, Dr. Johnson has strived to break down barriers in medical informatics, and his work on MIMIC-III demonstrates the immense potential of publicly available data. His research interests include retrospective observational research, machine learning, and new approaches to modeling heterogenous clinical data.


Dr. Johnson runs the Knowledge in Data (KinD) lab in Child Health Evaluative Sciences program at SickKids Research Institute. The lab focuses on retrospective observational studies to generate new knowledge, predictive modeling using machine learning to prognosticate outcome, and curating data to support the research enterprise. Dr. Johnson’s research interests include machine learning, natural language processing, and critical care.
