Sevi Modestou

I am an isotope geochemist and paleoceanographer using various isotopic tools to understand Earth's past climate. In particular, I work with 'clumped isotopes' to understand past temperature change on Earth (as well as within other planetary bodies). I also utilise stable, radiogenic and cosmogenic isotopes in the context of paleoclimatology and paleoceanography, and the evolution of the earth.

I manage the NICEST Lab at Northumbria University, where we make analyse various materials, including fossils, speleothems, other carbonate minerals, soils and sediments, and water. More specifically, my lab focuses on the Δ47, δ13C and δ18O composition of carbonates, δD and δ18O of water, and the δ13C and δ15N of organic materials including sediment.
