I am an Associate Professor
of Theoretical Physics
and Cosmology in the
Department of Physics and Astronomy at the University of British Columbia in Vancouver.
I am interested in cosmology, its application to tests of known and unknown physics, and related theoretical physics and astrophysics.
My recent research involves constraining model-independant properties of particle dark matter, the physical effects of dark-sector particles in the early Universe and its subsequent evolution,
the cosmic microwave background (CMB) radiation, and exciting prospects for using cosmic 21-cm fluctuations to constrain inflation
and the standard cosmological model.
