Summary
👤
Senior🎓
Top SchoolMiriam Kreher is an R&D engineer at Los Alamos National Laboratory with a decade of experience advancing computational reactor physics, nuclear data, and non-proliferation analysis. She completed a PhD at MIT’s Nuclear Science & Engineering department and a Metropolis Postdoctoral Fellowship at LANL, where she now applies Monte Carlo methods to reactor analysis in the Global Security directorate. Miriam has contributed substantive back-end enhancements to the widely used OpenMC Monte Carlo code, extending multi-group cross section capabilities and restoring critical physics features. Her work blends deep numerical methods—transient Monte Carlo, temperature feedback coupling, and eigenvalue/depletion solvers—with practical tooling for high-performance simulation workflows. Beyond the lab she’s driven outreach and leadership through the American Nuclear Society and large student conferences, evidencing strong programmatic and fundraising skills alongside technical excellence.

Contributions summary:Miriam primarily focused on extending the functionality of the OpenMC Monte Carlo code. Their contributions included adding new features to the multi-group cross section (MGXS) classes, specifically integrating support for current calculations and expanding the types of MGXS available. They also restored and updated existing, but out-of-date, code related to these new features to align with the current development branch. These changes suggest a focus on improving the core physics capabilities of the simulation code.
