Research

I am a theoretical astrophysicist interested in a wide variety of topics including accretion disk dynamics, magneto-hydrodynamics, compact objects, Gamma Ray Burst physics, tidal interaction, protoplanetary disks, planet migration, planet formation, extrasolar planets, and gravitational wave physics. My thesis, under my PhD advisor Dong Lai at Cornell University, explored global instabilities of black hole accretion disks, in particular of diskoseismic modes. I also have done work on the physics of gravitational wave detectors, planet migration and the distribution of extrasolar planets, and neutron star physics of short Gamma Ray Burst progenitors. Recently I've started working on pulsar and magnetar physics, and on variational principles for nonconservative dynamics, with my collaborators Chad Galley and Leo Stein. You can find a list of my papers through NASA ADS.

My work has also been featured in a few popular science articles at APS Physics, New Scientist, and Ars Technica.
