I am interested in and work on dynamic simulations of various astrophysical objects and processes with the goal of explaining the underlying physics in conjunction with multi messenger observation data. I am particularly interested in ultra-high energy processes as these offer us a window into regimes that are otherwise inaccessible through colliders and other terrestrial experiments. Sources of interest to me include AGNs, supernovae, binary neutron star mergers, binary black hole mergers, etc.
