About

Welcome! I am a postdoctoral researcher working in theoretical astrophysics at the Tsung-Dao Lee Institute and Cornell University. I specialize in astrophysical applications of 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 facilitate the growth of planets orbiting around young stars. I focus on the oscillations and instabilities 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 study the effects of rapid rotation on such oscillations.
