Summary
👤
Senior🎓
Top SchoolSam Hatfield is a computational scientist at ECMWF specializing in making weather and climate models faster and more efficient through reduced-precision arithmetic and high-performance computing. With a DPhil from Oxford in atmospheric physics and over a decade of technical experience, he has ported and optimized forecasting models for leading supercomputers (including Frontier) and contributed open-source tooling such as ecTrans. His work bridges research and operational forecasting—implementing single-precision NEMO and exploring modular supercomputing architectures via EuroHPC—so theoretical gains translate directly into improved numerical weather prediction. An engaging science communicator, he built a mini weather-simulating supercomputer and finished runner-up in Famelab UK, combining technical depth with public-facing storytelling.
