I am an Assistant 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.
