Dr. Seely’s education includes an undergraduate honours in physics at Carleton University, followed by medical school, general surgery training, and a doctoral degree in basic science from McGill University, and thoracic surgery and critical care medicine training at the University of Ottawa. Dr. Seely’s scholarly interests include: 1) theoretical research exploring the clinical insights of complex systems science (e.g. emergence, uncertainty and dissipation); 2) physiologic understanding of complex biologic variability; 3) applied research monitoring multi-organ variability during exercise, onset and resolution of infection, critical illness and weaning and in the prediction of likelihood of organ donation success following Donation after Circulatory Death (DCD); and 4) development and implementation of a systematic means to continuously monitor all adverse events after all surgery, as well as provide feedback of that information to improve surgical care. Dr. Seely has supervised several graduate students and built research teams, has published over 210 peer-reviewed papers, presents annually at international meetings and has been awarded over $8.7 M in competitive grant funding. He shares his family life with Kathy Patterson and their daughters Phoebe and Ruby in Ottawa.
