I am interested in astrophysical phenomena which are characterized by relativistic gravity and extreme states of matter. Progress in understanding systems such as binary black holes, binary neutron stars, collapsing neutron stars, and gamma ray bursts is often made through numerical simulations. My recent activities have centered on developing codes for evolving Einstein's equations of general relativity coupled to the equations of magnetohydrodynamics. These codes have been used to study the evolution of magnetized hypermassive neutron stars and magnetized core collapse.

Recent publications:
