PhD students who wish to be supervised by Perimeter Institute faculty normally apply through the __PSI program__. To apply directly to a PhD program, students should submit an application to the Physics and Astronomy Department at the University of Waterloo.

Students interested in pursuing an MSc degree should apply to Perimeter Institute's __PSI program__.

E. T. Jaynes famously described quantum theory as an omelette of epistemological and ontological elements, all scrambled up in a way that no one has yet seen how to unscramble. The focus of my research program is to try and unscramble this omelette. In particular, I am pursuing the idea that quantum states are representations of an agent's incomplete knowledge of a system and that much of the formalism of quantum theory is best understood as a theory of Bayesian inference. On the more practical side, I have been working on quantum resource theories, in particular, the resource theories of quantum states that break symmetry and quantum states that are out of thermal equilibrium.
