Eleanor’s research interests focus on major climatic and oceanographic changes on timescales spanning several tens of thousands to several hundreds of millions of years. She is particularly interested in how isotope and trace element proxies in ancient marine biogenic calcite (foraminifera, brachiopods, corals) can help us reconstruct and disentangle the causes and effects of such climate change. In recent years, her research has also involved a focus on how fossil assemblages of planktonic foraminifera can contribute to our understanding of major oceanographic changes in the past.
She has undertaken fieldwork in Mexico, China, Belgium, Poland, the UK, Spain and now Fiji. Much of her work has utilized samples recovered from deep-sea drilling programmes, namely the Integrated Ocean Discovery Programme (IODP), and she had the privilege of sailing on IODP Expedition 350 (Izu Bonin Reararc Basin) during April-May, 2014.
