Rockstar🎓
Top SchoolPeter Brady is a scientist and computational engineer with 12 years of experience developing numerical algorithms for large-scale, high-performance simulations of turbulent multiphase flows in complex geometries. Based at Los Alamos National Laboratory, he focuses on exascale-ready, massively parallel methods and has a strong track record from GPU-scale runs to production code verification using the method of manufactured solutions. His open-source contributions span build and CI/CD automation for SymEngine, algorithmic improvements in SymPy, and packaging expertise in Spack—demonstrating both low-level C++/Python work and ecosystem-level reproducibility. He earned a PhD in Aerospace Engineering and has repeatedly reduced computational cost and increased robustness for community-scale codes, including pioneering 3D drop-breakup simulations that ran on thousands of processors. Less obvious: he pairs deep numerical research with practical DevOps skills, making him effective at taking research codes to sustainable, high-performance production.
