University of Waterloo
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.
I am a "data-oriented" cosmologist: my work is a mixture of theoretical physics,
phenomenology, computational physics, statistics, and data analysis. I have been
a member of several large experiments: the WMAP and Planck cosmic microwave background
(CMB) satellites, the CAPMAP and QUIET CMB experiments, and recently the HSC survey,
a new experiment to observe distant galaxies using a new camera on the 8-meter Subaru
telescope. Outside the these experiments, my best-known work is on CMB data analysis
and phenomenology, including a classification of observable signals from self-interactions
of the inflaton, and the first detection of gravitational lensing in the CMB.
Recently, I have been interested in problems in cosmological large-scale structure,
for example simulating initial conditions for N-body simulations with quantum mechanically
generated initial conditions, in interacting models of inflation such as DBI inflation.
