Biography

John obtained B.Sc. and Ph.D. degrees in mathematics from the University of British Columbia and an M.Sc. degree in mathematics from the University of Toronto. His main research interests are in experimental design, foundations of statistics, statistical decision theory and computer experimentation, and he has supervised a number of graduate students working in diverse areas of statistics. His research has been funded by the Natural Sciences and Engineering Research Council of Canada. John has consulted and collaborated extensively with companies and organizations in Manitoba, and has given a number of workshops on experimental design in the aerospace, agri-food, mining and semiconductor sectors. John is a former Director of the Institute of Industrial Mathematical Sciences in the Faculty of Science and a former Director of the Statistical Advisory Service in the Department of Statistics. He has been actively involved in professional organizations, having served as President of the Statistical Society of Canada (SSC), President of the Statistical Association of Manitoba, Secretary of SSC, President of the Business and Industrial Statistics Section of SSC and Chair of the Publications Committee of SSC. He is a past recipient of the Dr. & Mrs. H.H. Saunderson Award for Excellence in Teaching at the University of Manitoba. John retired as Professor and Head of the Department on December 31, 2011; he is now a Professor Emeritus.
