To me, it's a very unique opportunity to study the history of our climate. It is a privilege to be able to use ice cores, sediment cores, as a time capsule, and understand what has happened in the past.

My PhD looked at reconstructing past ocean circulation in the Southern Ocean. So essentially, I used sediment cores, and then looked at specific little microfossils. And this provided a chemistry or a signature of past ocean circulation and then I was able to look at reconstructing climate over the last 160,000 years.

In my current work I've been looking at ice cores from Law Dome that go back about 90,000 years. With the ice core, the ice cores are a record of what happens in the atmosphere. I tend to think of them as an archive or a library of past climate information. So we have different tools, different scientific instruments, and we can look at the different layers in these different cores.

It is a privilege to be able to access parts of our history.

Research interests

My research is focused on palaeoclimate — ‘past climate’. I have been lucky enough to work with national and international research teams that use ice core and marine sediment records that can be used to reconstruct past climate conditions.

In my current role as an Ice Core Research Scientist at the Australian Antarctic Division, I work with a team that uses ice core records to understand past and present climate variability, and change, with particular emphasis in the Australian Antarctic Territory, the Southern Ocean, and Australian sub-Antarctic territories. Our work uses existing and recently collected ice cores from East Antarctica to continue the development of ice core records and climate reconstructions, to explore climate processes, and to improve the calibrations and interpretations used in ice core studies.

I am currently using water isotopes of oxygen and hydrogen (deuterium) in ice cores from East Antarctica to look at changes in snowfall, temperature, atmospheric composition, and atmospheric circulation. These records will help us to understand, quantify and determine the natural variability of climate processes, and changes caused by human activities.

Prior to working at the Australian Antarctic Division, my PhD and post-doctoral research used micro-fossils from marine sediment cores and sediment traps from the South Tasman Rise region to reconstruct past deep water circulation and carbonate chemistry in the Southern Ocean, and to study the effects of ocean acidification (caused by increasing amounts of carbon dioxide dissolving in the ocean) on calcareous shelled organisms in the Southern Ocean.

I have a background in Earth Sciences and have previously worked as a mine geologist in northern Queensland.
