Rockstar🎓
Top SchoolKeeran Rothenfusser is a software engineer with a PhD in Scientific Computation, blending deep numerical and mathematical expertise with hands-on systems engineering for HPC and telecom. He has driven optimized numerical libraries and performance tooling at Arm—translating multigrid and linear-algebra research into production-grade BLAS/LAPACK kernels and 5G PHY routines—and now extends that work to RISC-V at Rivos. Keeran combines C/C++, Python and Fortran fluency with practical experience in performance analysis, debugging and co-design across multiple Horizon 2020 exascale projects, where he also handles administrative and partner-facing responsibilities. Based in Munich, he brings a researcher's rigor to real-world optimization problems and a track record of turning algorithmic insight into measurable performance gains.
