Summary
👤
Senior🎓
Top SchoolFlorent Mertens is a Junior Professor and observational cosmologist with 18 years of experience probing the first billion years of the Universe via the 21-cm signal of neutral hydrogen. He leads and co-leads major campaigns with NenuFAR and LOFAR, developing end-to-end pipelines, calibration strategies, and analysis tools that delivered some of the most stringent constraints at redshifts z~8–20. Based at Observatoire de Paris, he also serves as France’s representative in the SKA CD/EoR Science Working Group and as a support scientist in the SKA SRCNet Science Delivery team, preparing workflows for next-generation SKA data. His background bridges software engineering and astrophysics—from building wavelet-based imaging tools for AGN jets to enterprise and ground-segment systems—enabling robust, production-ready analysis of challenging low-frequency interferometric data. Notably, he pioneered a Gaussian Process framework for foreground separation integrated into LOFAR pipelines, combining methodological innovation with large-scale observational leadership.
