AFFILIATIONS

University of Waterloo and University of Guelph

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.

Research Interests

Understanding gravity in strong/highly dynamical regimes. In
particular study of systems able to produce strong gravitational
and electromagnetic signals. Tests of alternative theories of gravity
and how to do so with upcoming gravitational wave detectors.
Understanding gravitating systems in higher dimensional scenarios.
Explorations of AdS/CFT in dynamical settings (quantum quenches and gravity/fluid correspondence)
Understanding of bubble collisions in non-linear regimes.
