Summary
👤
Senior🎓
Top SchoolAlexandra Macedo is a research-focused software engineer with nine years of experience building high-performance scientific software for gravitational-wave physics and detector characterization. As a research assistant at CSUF’s GWPAC and collaborator with Caltech and the international SXS team, she has contributed core C++17 back-end work to SpECTRE—implementing expressive tensor libraries and Einstein-equation evolution systems used in numerical relativity simulations of black hole and neutron star mergers. She pairs a strong academic foundation (MS in Computer Science from UCSD, MS work in Physics at CSUF, and a UCLA BS in biology) with practical engineering: automated grading systems for large CS courses and ML-driven noise characterization tools for LIGO. Colleagues know her for translating mathematical notation into clean, efficient code interfaces that make complex tensor algebra more ergonomic and performant.
