I am a theoretical astrophysicist using computer simulations to understand the physics of plasmas near extreme objects such as neutron stars and black holes. My main tool is a "Particle-in-Cell" code Aperture that I developed over the past few years. It simulates ultra-relativistic plasmas in strong electromagnetic fields, and their interaction with high-energy radiation. The code runs on GPUs, is highly optimized, and enables me to run simulations on my personal workstation that would otherwise take thousands of CPU cores. I also work on interactive visualizations of astrophysical simulations in the modern browser.
