Research
I am a professor of theoretical astrophysics at the University of Toronto, working on the fluid dynamics of gravitational collapse and energetic feedback in:
 -  star and star cluster formation,
 -  molecular cloud evolution and the interstellar medium,
 -  black hole formation and accretion,
 -  stellar tidal disruptions,
 -  supernovae, gamma-ray bursts, and related transients.
