Position: PhD Student, Research School of Earth Sciences, Australian National University

Area of Study: Oceans and Climate Change

Project: Sea-level changes over the mid-Pleistocene Transition

What does that mean?

The mid-Pleistocene transition is a time when Earth’s global climate cycles underwent a fundamental change, between 1,250,000 and 700,000 years ago. The main result was a change in glacial cycle duration and an intensification of ice ages, and the reason why this happened is still a mystery.

My research looks at reconstructing sea-levels, and therefore ice-volume over this time period.

To do this I am using foraminifera, microscopic organisms whose calcite shells get buried and preserved in sediments on the seafloor, recording information on past climate.

How did I get here?

I studied Oceanography at the University of Southampton with a year abroad at the University of Miami. After finishing my masters I worked in industry for a couple of years as a hydrographic surveyor doing seafloor mapping, but I missed science too much! So I started my PhD… moving to Australia to do it was an added bonus!
