Bonjour !

I am a postdoctoral researcher in geochemistry and paleoceanography in the Climate team at CEREGE. My work focuses on the development and application of high-precision isotopic and elemental analyses to reconstruct past ocean chemistry and climate variability, with a particular emphasis on boron isotopes in marine carbonates.

Passionate about understanding past climate–ocean interactions, my aim is to improve reconstructions of seawater pH, atmospheric CO₂, and biogeochemical cycles over geological timescales, in order to anticipate ongoing and future climate change. My research lies at the interface between analytical (geo)chemistry and paleoceanography, combining methodological developments in mass spectrometry with their application to paleoenvironmental archives such as foraminifera.
