Computational astrophysicist · Princeton University
Hi, I’m Marcus DuPont.
I use supercomputer simulations to study exploding stars, black-hole environments, and some of the brightest events in the universe.

about me
I study what happens when matter moves at nearly the speed of light around exploding stars and black holes. These extreme events can briefly outshine entire galaxies, but many of the forces driving them cannot be observed directly. Computer simulations let me test the physics behind what telescopes see.
I focus on supernovae, gamma-ray bursts, and other short-lived cosmic explosions. I developed SIMBI, a simulation code that runs on CPUs and NVIDIA or AMD GPUs, to model fast-moving gas, shocks, magnetic fields, and strong gravity. I’m especially interested in accretion—matter falling toward a compact object—and bow shocks, the curved shock waves made as objects move through surrounding gas.
