Research

I am a computational astrophysicist specializing in black hole accretion. I am interested in combining the effects of general relativity, magnetohydrodynamics, and radiative transfer in order to model accretion flows in a variety of systems.

A key tool for this is Athena++, a successor to the MHD code Athena. My role as an Athena++ developer is combining the strength of Athena's MHD with GR, enabling us to run simulations in arbitrary stationary spacetimes.
