Christoph Conrads
PhD Candidate Exascale Computing
Germany
Summary
👤
Senior🎓
Top SchoolChristoph Conrads is a PhD candidate in Exascale Computing at Forschungszentrum Jülich with nine years of experience building high-performance numerical software and optimizing algorithms for real-world quantum-mechanical simulations of solar cells. He brings deep expertise in numerical linear algebra, C++, Fortran and Python, and a track record porting and tuning code for diverse architectures from microcontrollers to TOP500-class HPC systems. His open-source work includes maintenance and package contributions to Spack and documentation and correctness improvements in LAPACK, reflecting a focus on reproducible, portable scientific software and dependency hygiene. Prior roles span in-situ data analysis for exascale systems at Inria, low-power DSP ports for Cortex-M, and concurrency-focused blockchain tooling, demonstrating both low-level performance engineering and broader system design. Colleagues rely on him for bridging applied research and production-grade implementation, often uncovering subtle numerical and build-system issues that others miss. Based in Germany, he combines rigorous academic training with hands-on engineering across the full stack of scientific computing.
