Aaron Fisher
Director Of High Performance Computing For Energy Innovation Program
Livermore, California, United States
Summary
🤩
Rockstar🎓
Top SchoolAaron Fisher is a director-level computational scientist who has spent three decades turning multiphysics CFD and high-performance computing into practical gains for industry and national labs. As director of the HPC4EnergyInnovation program at Lawrence Livermore National Laboratory he connects national laboratory computational expertise with U.S. manufacturers to improve energy and carbon efficiency across industrial processes. His career began with simulation and tooling for next-generation lithography at Sandia and evolved through academic work that produced 10x algorithmic speedups and full-wave nonlinear electrodynamics models. A hands-on developer and open-source contributor, he has made substantive backend and build-level contributions to widely used projects such as MFEM and Spack, improving parallel builds and finite-element integrator robustness. He combines deep numerical-analysis chops (Ph.D. in applied science) with program leadership, uniquely positioning him to translate research-grade simulation capabilities into deployable, energy-saving engineering solutions.

mfem/mfem
Oct 2015 - Dec 2022
Lightweight, general, scalable C++ library for finite element methods
Role in this project:
Backend Developer
Backend DeveloperContributions:203 reviews, 190 commits, 23 PRs in 7 years 2 months
Contributions summary:Aaron primarily contributed to the MFEM library by addressing bugs and implementing new features related to the finite element methods. They fixed a segmentation fault within the `CurlCurlIntegrator` and added version and configuration strings. Further, the user introduced a global output stream mechanism to redirect output and a global MPIComm to replace MPI_COMM_WORLD and refactored existing files to use the new `mfem::out` and `mfem::err` output. This included modifications to multiple files within the codebase demonstrating broad involvement with the libraries architecture and its integration with the build system.

spack/spack
Oct 2017 - Mar 2018
A flexible package manager that supports multiple versions, configurations, platforms, and compilers.
Role in this project:Backend & Build Engineer
Backend & Build EngineerContributions:9 reviews, 5 commits, 9 PRs in 5 months
Contributions summary:Aaron primarily contributed to the `mfem` package within the `spack/spack` repository, focusing on version updates and dependency management. They added and updated various versions of the `mfem` package and its dependencies. Furthermore, the user fixed build issues and updated configurations to integrate with different libraries and tools like MPI. This involved modifying the `package.py` file to reflect changes in external libraries and build configurations.
