Areas of research:
If you are interested in pursuing a MSc degree, please apply to the Perimeter Scholars International (PSI) masters program. If you are interested in working with me as a PhD student, please submit an application directly to my department at the University of Waterloo and indicate that you would like to be supervised by me. Perimeter Institute is committed to diversity within its community and I welcome applications from underrepresented groups.
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
