Summary
👤
Senior🎓
Top SchoolRoland Haas is a Scientific Software Developer with 16 years of experience building high-performance numerical infrastructure for gravitational-wave and multimessenger astrophysics. He develops and maintains waveform modeling and simulation tools—leveraging numerical relativity, relativistic (magneto-)hydrodynamics, and black hole perturbation theory—to produce template banks used by detectors like LIGO and Virgo. His career spans research programming roles at leading institutions (UBC, NCSA, Max Planck, Caltech, Georgia Tech), combining production-grade software engineering with deep domain expertise from a PhD in physics. Roland specializes in mesh refinement, elliptic solvers, and extreme mass-ratio inspiral/self-force problems, translating complex theory into robust, scalable code for HPC environments. He often bridges the gap between simulation and data analysis, focusing on electromagnetic counterparts and the nuclear equation of state inferred from neutron star mergers. Based in Vancouver, he brings a rare mix of hands-on scientific computing and long-term research program continuity that accelerates detector-ready waveform delivery.
