My research program centers on the use of large-scale direct numerical simulations to study the gas dynamics of a wide range of astrophysical systems, from protostars to clusters of galaxies. Almost all of this work requires development of advanced numerical algorithms for astrophysical gas dynamics on modern parallel computer systems. For example, I am one of the primary developers of the ZEUS code for astrophysical MHD, and more recently my collaborators and I have developed Athena, a high-order Godunov scheme for astrophysical MHD that uses adaptive mesh refinement (AMR).
