Postdoctoral Fellow

My PhD research focussed on reconstructing Australian Quaternary palaeo-environments, using palaeolimnology, and the stable & clumped isotopic composition of various carbonate phases.

After finishing my doctorate, I held a Postdoctoral Research Associate position at Washington University in St. Louis, where I used proxy records for the stable isotopic composition of environmental waters through the Common Era to investigate changes in global hydroclimate. I also used water isotope observations alongside palaeoclimate proxy data to investigate variability in tropical Pacific atmospheric circulation through the last millennium.

I have also worked as a Marine Scientist for Geoscience Australia, where I mapped and analysed seabed morphology.

Outside academia, my interests are many & varied: some edited highlights include cross country & alpine skiing, open water swimming, hiking, reading fantasy novels, and playing assorted musical instruments.

Research interests

I use climatic information from the Common Era (the past ~2000 years) to contextualise modern climate change. Specifically, I seek to develop 'pre-industrial climatic baselines' against which we can assess the influence of human activities on Earth's climate. For this, I integrate information from palaeoclimate proxies, modern observations, and climate model simulations.

I have a particular focus on hydroclimatic variability; that is, understanding the nature and drivers of variability in the water cycle. The main research tool I use is the stable isotopic composition of water, which is an integrative tracer of many water cycle processes. As well as observational and climate model data, I use water isotope proxy data from multiple archives including:

  • lake & marine sediments
  • glacier ice
  • corals & other marine carbonates
  • terrestrial & marine molluscs
  • tree rings
  • speleothems (cave carbonate)

I also have a particular interest in the influence of the tropical Pacific on global hydroclimate.
