Biography

George is an isotope geochemist and palaeoclimatologist working on reconstructing past environmental changes over the last three million years from marine and lake sediment cores. He is also a visiting research associates at the British Geological Survey/NERC Isotope Geosciences Facility. George's research is focused towards:

• Developing and applying diatom isotopes δ¹³C, δ¹⁸O and δ³⁰Si) in environmental reconstructions;
• Constraining biogeochemical cycling and the global silicon cycle;
• Investigating Quaternary changes in meltwater influx and role of the biological pump in CO₂ sequestration in high latitude marine regions, including the Bering Sea and North Atlantic, North Pacific and Southern Oceans;
• Reconstructing Pliocene palaeoceanography during the onset of major Northern Hemisphere Glaciation;
• Reconstructing the Quaternary/Pliocene climatic and environmental history of lacustrine systems in Siberia.
