Summary of Research

My primary research interests are in computational and nuclear astrophysics. I mainly work on a project aimed at using multidimensional hydrodynamics simulations to study the explosion mechanism underlying Type I X-ray bursts, which are massive thermonuclear explosions on the surfaces of neutron stars. Specifically, the study focuses on the growth and propagation of thermonuclear vortices that form on the surface of the star during these events. Developing a better understanding of the physical processes underlying the explosion can help to explain observable features of X-ray bursts and would potentially aid in constraining the nuclear equation of state.
