Summary
🤩
Rockstar🎓
Top SchoolStefan Henneking is a computational scientist and research software engineer with nine years of experience building high-performance numerical software and finite element tools. Based at the Oden Institute at UT Austin and now located in Seattle, he combines a PhD in computational science with hands-on C++ development—contributing device-enabled, complex-number support and partial-assembly features to the widely used MFEM finite element library. His background spans national labs (LLNL, Sandia), industry internships at Amazon/AWS, and academic fellowships, giving him fluency in both research and production-grade engineering. Stefan’s work bridges deep numerical methods and practical software engineering, often optimizing operator implementations for scalable, heterogeneous hardware. He brings a track record of shipping robust backend features that enable advanced simulations rather than just prototype code.
