Summary
👤
Senior🎓
Top SchoolMarc De Frahan is a Senior Developer Technology Engineer specializing in GPU-enabled and AI-powered numerical simulations for energy and high-energy-density applications, now at NVIDIA after a decade in computational science. He combines deep expertise in C/C++ GPU programming (CUDA, HIP, Kokkos), Python ML (TensorFlow, PyTorch), and high-order numerical methods like Discontinuous Galerkin to accelerate multi-GPU exascale workflows. His Ph.D. work at the University of Michigan applied supercomputing to fluid and wave interactions across domains from supernovae to combustion and biomedical therapies, reflecting a rare breadth between fundamental physics and production-grade software. At the National Laboratory of the Rockies he moved research prototypes toward scalable HPC implementations and contributed practical packaging support to spack/spack, expanding access to community simulation tools like amr-wind and openfast. He enjoys science outreach and translating complex ideas for diverse audiences, taking particular delight in sparking that “aha” moment in learners. Based in Golden, Colorado, Marc blends rigorous applied mathematics training with hands-on GPU and ML engineering to drive performant, real-world simulation systems.
