I’m currently working on algorithms for modeling reactive astrophysics flows, applying these to studies of X-ray bursts, Type Ia supernovae, stellar convection, and novae.

My main work is on the suite of AMReX-Astrophysics codes: Castro (for compressible flows) and MAESTROeX (for low Mach number stratified flows). These are designed to run on supercomputers (using CPUs or GPUs) and model reacting astrophysical flows.

I also build the pynucastro library: a library for exploring nuclear reaction rates.

I am also very interested in making teaching resources (especially for computational astrophysics) freely available, including:

• My open text Introduction to Computational Astrophysical Hydrodynamics introduces the core finite-volume methods used in astrophysics simulation codes.

• The teaching and protyping code pyro.

• My introductory astronomy animations.
