Summary
👤
Senior🎓
Top SchoolJoe Beisman is a software engineer and physical scientist with nine years of experience building high-performance, physics-driven simulation software and geometric algorithms. He has led development of performance-portable land-surface physics packages and contributed production-grade multiphysics simulators coupled to large Earth system models, with expertise spanning HPC parallelism, GPU programming, and scalable numerical methods. His work bridges applied mathematics, computational geometry, and nonlinear optimization—delivering robust solvers for sparse systems, complex unstructured meshes, and coupled multiphysics problems. Joe has operated across national labs, startups, and consulting, translating research-grade algorithms into production infrastructure for climate, weather, and subsurface modeling. Now at Velo3D, he focuses on geometric algorithms where his background in meshing, discretization, and performance tuning uniquely positions him to solve challenging computational-geometry problems in manufacturing contexts. Notably, he pairs deep domain knowledge from a PhD in hydrologic science with hands-on HPC and modern C++/Python/Julia engineering to optimize real-world large-scale simulations.
