PROFILE
Justin Laughlin
Worked on the mfem/mfem repository, delivering core enhancements to mesh processing and NURBS workflows using C++ and CMake. Developed robust algorithms for knotvector mapping, patch retrieval, and mesh topology orientation correction, addressing both 2D and 3D cases. Improved numerical reliability by fixing matrix-vector product operations in finite element kernels and expanded test coverage with new meshes and unit tests. Refactored and cleaned up code to improve maintainability, readability, and performance, while updating documentation to support new features. Focused on algorithm development, code refinement, and build system management, resulting in more reliable, extensible, and maintainable computational geometry infrastructure.

Apr 1, 2025April 2025 MFEM work summary focusing on reliability and demonstration of NURBS-related features. Implemented robust edge-to-knot mapping for NURBSExtension, added GetEdgeToKnotMapping, refactored topology loading to ensure edge-wise consistency in knot-vector assignment, and improved debug output. Delivered an experimental NURBS demo (demo.cpp) and updated build system; the demo was deprecated and removed from build and source as part of cleanup. Overall, these efforts improved correctness, maintainability, and demonstrated business value of NURBS-based reconstruction workflows.
