Summary
👤
SeniorHyun Lim is a computational/theoretical physicist and staff scientist at Los Alamos National Laboratory with nine years of experience developing high-performance multi-physics simulation codes for gravitational physics, astrophysics, and shock-driven problems. He leads development of performance-portable GR radiation-MHD, differentiable hydrodynamics, and radiation transport modules, and has a strong numerical-analysis background in preconditioners and PDE solvers. His work spans black hole and neutron star mergers, beyond–general-relativity dynamics, and inverse problems where he applies physics-informed machine learning and symmetry-constrained models for density reconstruction. An active open-source maintainer (github.com/hlim88), he uniquely bridges foundational ML, Lie-analysis symmetries, and production-grade simulation toolchains—now while pursuing a JD+MBA at Kellogg.
