Summary
👤
Senior🎓
Top SchoolScott Kruger is a physicist and computational scientist with over 20 years building high-performance scientific software and leading multi-institutional, DOE-funded projects in plasma physics for fusion and semiconductor manufacturing. He combines deep expertise in scientific computing frameworks, reproducible scalable simulations, applied mathematics, and machine learning to solve physics-first engineering problems. As a technical manager and principal scientist, he has mentored teams, grown commercial revenue through customer-focused processes, and driven projects like EFIT-AI, SWIM, FACETS, and NIMROD from research to impact. His open-source contributions to foundational projects such as PETSc and Kokkos emphasize robust test automation and build reliability—work that quietly improves trust in scientific codes used by many researchers. Based in Boulder, he blends hands-on backend and automation engineering with strategic leadership, making complex simulation stacks maintainable and production-ready. He holds a Ph.D. in Nuclear Engineering and Engineering Physics from UW–Madison and a BS from Purdue, grounding his applied software work in rigorous physics training.
