Research interests

My research interests are in understanding how the isotopic chemistry of mammalian teeth can be used to reconstruct past climates. Specifically, I am interested in: using the oxygen isotope values of mammal teeth to quantify past temperatures and reconstruct climatic variability, and using the carbon isotope values of bones and teeth to understand changes in the environment and mammalian diets.

 

PhD: Stable isotopes in small mammal dental carbonate: investigating their applications for reconstructing Quaternary climate variability

 

My thesis aimed to: 1) investigate the sources of isotopic variability in modern and late Holocene rodent populations across the UK, 2) establish a robust modern relationship between the oxygen isotope compositions of rodent teeth and local meteoric water, 3) test whether the coupling of oxygen isotope values of rodent tooth and freshwater shell carbonates can produce reliable temperature estimates for Pleistocene interglacial stages in the UK, 4) examine whether millennial-scale climatic fluctuations can be identified using the isotope compositions of rodent teeth from two stratified Pleistocene cave sequences, and 5) investigate how past environmental and dietary changes are reflected in the carbon isotope values of rodent teeth.
