Summary
👤
Senior🎓
Top SchoolErwan Pannier is a CTO and co-founder with a decade of experience at the intersection of plasma physics research and cleantech entrepreneurship, building local carbon-neutral hydrogen production systems from lab to pre-industrial demonstrator. He earned a PhD in plasma-based CO2 conversion and translates deep experimental and computational skills—molecular spectroscopy, fast electronics, Python data tooling—into robust hardware and software for real-world energy applications. At Spark Cleantech he leads technology development for non-thermal plasma reactors while maintaining active research ties at CentraleSupélec and collaborative experience at Stanford. Beyond tech, he co-founded an eco-union to reshape workplace roles in the energy transition, reflecting a rare blend of scientific rigor, product delivery, and social organizing. He also contributes to open-source testing and QA (notably improving reliability in the astroquery project), underscoring a pragmatic focus on system robustness across research and software.

Contributions summary:Erwan's primary contributions revolve around testing the `astroquery` package's functionality. Their work includes writing tests to ensure correct behavior of the `gunzip` utility, which is involved in handling compressed files. The user also refactored the testing setup by utilizing temporary files and directories for creating and verifying test files, which is intended to improve the test reliability and prevent permission errors. These contributions directly support the reliability and robustness of the astroquery package.
