About

Welcome! I am a postdoctoral researcher at the Canadian Institute for Theoretical Astrophysics (CITA). I focus on astrophysical fluid dynamics and magnetohydrodynamics, and I'm particularly interested in the dynamics of accretion disks, planets and stars. I also like snowboarding, yoga and rock climbing.

Research

  • Accretion disk dynamics

    Accretion disks fuel very bright emission from compact objects, and the growth of planets orbiting around young stars. I focus on the dynamics of eccentric accretion disks with elliptical streamlines.

  • Stellar and planetary oscillations

    The pulsations of stars and gaseous planets provide the most direct insight into their interior structure. I am particularly interested in Saturn's oscillations, and their effect on the planet's rings.
