My area of research is theoretical astrophysics. I study systems where basic physical effects can be isolated from astronomical complexities. Current projects include the non-linear dynamics of the cosmic neutrino background, 21cm intensity mapping, pulsar VLBI scintillometry, and Canadian Hydrogen Intensity Mapping Experiment CHIME.
Additional Interests
n-body and hydro simulations, origin of galaxy spin, dark energy: 21cm cosmology, BAO, absorber acceleration. FRB and pulsars: gravitational waves, wave optics, lensing
Education
