Larry Aagesen is a computational scientist with a decade of experience applying materials science and physics to large-scale simulation problems, currently modeling multiphysics phenomena at Idaho National Laboratory. He holds a PhD in Materials Science and Engineering from Northwestern and previously served in research roles at the University of Michigan, bringing academic rigor to applied engineering challenges. His contributions to the MOOSE open-source simulation framework—adding and refining boundary conditions and sintering models—demonstrate hands-on backend development that strengthens widely used multiphysics tooling. A former nuclear Surface Warfare Officer with operations management experience in industry, he blends disciplined systems thinking, experimental grounding, and production-oriented software engineering. Based in Idaho Falls, he is comfortable navigating both high-performance scientific code and the practical demands of national-lab scale projects.

Contributions summary:Larry primarily contributed to the implementation of the `MatNeumannBC` boundary condition, including its definition, tests, and documentation within the MOOSE framework. They also addressed comments and made adjustments to the `MatNeumannBC` and `PolycrystalDiffusivityTensorBase` parameters. The user further worked on the grand potential sintering model, including fixing headers, re-gold tests, and adding documentation. These contributions focused on extending and refining the core functionality of the simulation environment.
