I am a PhD student based at both the School of Earth and Ocean Sciences at Cardiff University, and the Earth Sciences department at The Natural History Museum, London, UK.

I use the shells of microfossils that were once living unicellular organisms (planktonic foraminifera) to reconstruct past climate. These microorganisms once inhabited the surface regions of the oceans, and the varying chemical composition of their shell reflects the temperatures of the waters in which they lived. I am reconstructing the sea surface temperatures back to about 55 Million Years ago, a geological interval also known as the early Eocene, when the Earth was in a greenhouse state (super-warm). We are interested in greenhouse phases because they give us insight into how the Earth system as well as climate behave under extreme warmth. The Indo-Pacific Warm Pool is currently the warmest surface region of the oceans, and can thus help us understand what peak temperatures the oceans may have reached in the past.

I am affiliated to the Living and Changing research Themes within the School of Earth and Ocean Sciences.
