Summary
👤
Senior🎓
Top SchoolSebastien Villaume is an experienced scientific programmer and HPC specialist with nine years focused on numerical weather prediction, metadata standards and large-scale data management at ECMWF. He chairs the WMO expert team on NWP metadata and contributes to international data format standards (GRIB, BUFR, NetCDF), blending deep domain knowledge in NWP with practical software engineering in Fortran, C/C++, Python and Unix/Linux. His background in quantum chemistry and computational physics underpins a strong numerical-analysis mindset applied to atmospheric modelling and system design, including administration of multi-hundred-terabyte archives. Known for bridging research and operational needs, he combines hands-on coding and HPC optimisation with strategic initiative and team animation across international working groups. An uncommon strength is his ability to translate complex scientific requirements into metadata and data-exchange standards that enable discovery, publication and subscription at global scale.
