Rockstar🎓
Top SchoolPavol Juhas is a software engineer and computational scientist with 20 years of experience applying materials science and crystallography expertise to production software, currently at Google in Los Angeles. He holds a PhD in Materials Science and Engineering and has a strong background in atomic structure analysis, especially pair distribution function techniques, developed across roles at Brookhaven National Laboratory and Columbia University. Pavol is an active open-source maintainer whose contributions to the widely used quantum library Cirq improved code quality, testing, and build processes—demonstrating attention to long-term maintainability in complex scientific codebases. He blends deep domain knowledge in solid-state physics with pragmatic engineering practices, enabling reproducible scientific software and cross-disciplinary collaboration. An often-unseen strength is his focus on tooling and lint-driven correctness, which reduces technical debt in research software as it transitions to production.
