Background
I graduated from the Jesus College, University of Oxford with an MEarthSci (Hons) in Earth Sciences in 2005. For my final year research project, I investigated the prospects of developing a sea surface temperature proxy using stable strontium isotopes in coccolithophores calcite analysed by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS). The project was supervised by Dr Ros Rickaby.
In 2005 I moved to the school of Earth and Ocean Sciences, Cardiff University to conduct my doctoral research into middle Miocene climate dynamics, supervised by Dr Carrie Lear (Cardiff) and Dr Rich Pancost (Bristol). Using coupled organic and inorganic climate proxies, I constructed high resolution records of atmospheric pCO2 (alkenone and boron isotopes) and sea surface temperatures (foraminifera Mg/Ca and alkenone unsaturation indices). These proxy records, coupled with carbon system models and carbonate stable isotopes, allowed me insight into carbon cycle dynamics at a critical interval of major ice sheet growth in Antarctica.
Research
I am currently working as a research associate in the Organic Geochemistry Unit with Dr Rich Pancost, in collaboration with Dr Carrie Lear at Cardiff University. My research is focussed on developing high resolution sea surface temperature records using the TEX86 proxy at critical intervals of climate change in the Cenozoic, including the onset of the Paleocene-Eocene Thermal Maximum and the initiation of glaciation on Antarctica at the Eocene-Oligocene boundary.
