Research Interests

My research interests cover a broad range of theoretical astrophysics from 21cm cosmology to pulsar scintillation. Tools include N-body and fluid simulations (including the recent world's largest 3 trillion particle simulation on the PI wall) and radio telescopes such as CHIME and the Algonquin Radio Telescope
