Summary
👤
Senior🎓
Top SchoolTom Epperly is a senior scientific programmer and division leader with 15+ years driving high-performance computing and numerical algorithms at Lawrence Livermore National Laboratory. He blends deep domain knowledge in physical and chemical engineering (Ph.D., UW–Madison) with hands-on expertise in C, C++, Java, Python, and component-based architectures to deliver scalable mathematical modeling on supercomputers. Tom has led multiple R&D projects—most notably the Babel language-interoperability middleware and the Virtual Beam Line laser simulation—translating research prototypes into production-grade frameworks. As a manager he has grown and guided teams of researchers focused on optimization, parallel performance, and component technology across tokamak and engineering modeling efforts. He is as comfortable designing nonlinear optimization methods as he is shaping software architectures that let diverse languages interoperate at HPC scale. Based in Livermore, CA, he brings a rare combination of academic rigor, production software craftsmanship, and long-term stewardship of community-facing scientific tools.
