John Tse is a Professor in the Department of Physics and Engineering Physics at the University of Saskatchewan. His research focuses on the rationalization of the fundamental principles governing the structure, stability and thermodynamics of materials and the prediction of material behaviour. The objective is to provide the guiding principles for the rational design of novel functional materials. To achieve this goal, his research group has developed new theoretical models and implement new computational techniques. In many instances, they planned and performed synchrotron x-ray and neutron experiments to complement the theoretical studies.
