PhD title: A geological analogue for the future: the rapid climatic warming 56 million years ago
As one of several ‘Paleoclimate Reference Periods’ in the latest IPCC AR6 report, the Paleocene-Eocene Thermal Maximum (PETM): a period of abrupt global warming ~56 million years ago, provides one of the best analogues for investigating the impact of anthropogenically released carbon on the Earth system.
Previous research has primarily focused on the comparison of independent palaeontological or geochemical records from different PETM sites which introduces increased uncertainty from the influence of local processes, preservation, and age constraints.
Therefore, there is currently a paucity of PETM records that integrate palaeotemperature and palaeontological data, specifically from shallow marine settings that are particularly sensitive to the rapid climatic and biotic changes associated with the PETM excursion.
This project will use material collected from the Kheu section in the Caucuses to reconstruct the impacts of PETM sea surface and bottom water temperature change using a multi-proxy approach: (i) foraminiferal population data, (ii) δ18O, (iii) Mg/Ca, and (iv) Δ47.
The findings of my PhD research will contribute to our growing understanding of identifying the climatic and biological responses to abrupt global warming events like the PETM in the stratigraphic record.

Causal Research Assistant at the Lyell Centre
Hired for up to 12 weeks to assist in the picking and processing of a large sample set of planktonic foraminifera across the Last Glacial Maximum (i.e., Globigerinoides ruber) for organic carbon isotopes, under the supervision of Tommaso Paoloni; a PhD student of Prof Babette Hoogakker at Heriot Watt University. Alongside learning further sample preparation and cleaning techniques, I gained expert insight into the use of a Single Quadrupole Trace 1300 Gas Chromatograph-Mass Spectrometer/Flame Ionization Detector (GC-MS/FID) to better assess the amount of lipids (such as alkenones) present inside the foraminiferal organic membrane.
Quality control (Q/C) volunteer on the PhanTASTIC project
Volunteered to take part in the PhanTASTIC (Phanerozoic Technique Averaged Surface Temperature Integrated Curve) project, led by Dr Emily Judd; a postdoc of Dr Jess Tierney at the University of Arizona. Undertook quality control (Q/C) checks on collated foraminiferal δ18O stable isotope datasets, which involved checking for errors between the collated datasets and the raw data taken from the original publications and importantly flagging up if any dataset exhibited signs of diagenesis.
