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.

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.

AdS instability and implications on thermalization.

Turbulence, relativistic hydrodynamics and gravity

With the era of gravitational wave astronomy already started I'm also placing

considerable focus on the development of a framework with which to test

General Relativity through possible subtle effects of possible deviations. As well,

increasing efforts on multimessenger astronomy
