about me

[mdupont@eigendev ~]% cat ~/research/README.md

My research focuses on understanding the physics of astrophysical transients through computational modeling. I explore the gas dynamics of cataclysmic explosions—supernovae (SNe), gamma-ray bursts (GRBs), and Fast Blue Optical Transients (FBOTs)—using SIMBI, a three-dimensional special- and general-relativistic magnetohydrodynamics code I developed that runs on CPUs as well as NVIDIA and AMD GPUs. Currently I am particularly interested in accretion problems, dynamical systems, and the physics of bow shocks—especially how these phenomena interact in extreme environments involving ultra-relativistic speeds, strong shocks, and magnetic fields. My work combines numerical simulation with analytical theory to build self-consistent models that constrain the fundamental processes driving these catastrophic events, from the conditions preceding stellar death to the complex dynamics of matter in extreme gravitational and electromagnetic fields.
