I am interested in how Earth’s climates changed before humans started regularly writing down weather observations: understanding these past changes can give us clues as to what Earth’s climate may look like in the future. I am particularly interested in variability in the water cycle over the past 2000 years, on regional to global scales.
I am currently a postdoctoral fellow in the Research School of Earth Sciences at the Australian National University, where I am taking a palaeoclimate perspective to understand the dynamics and characteristics of Australian drought and fire weather extremes. This research is supported by the ARC Centre of Excellence for Climate Extremes.
Before starting at ANU, I was a postdoctoral research associate in the Department of Earth and Planetary Sciences, Washington University in St. Louis. There I investigated controls on modern spatial and temporal variability in the stable isotopic composition of precipitation, as well as using water isotope proxy records to investigate changes in tropical ocean-atmosphere circulation over the past millennium.
Prior to starting my academic career, I worked as various things, including as a marine scientist for the Australian government.
Aside from climate science, my interests are many and varied: some edited highlights include swimming, cross country and downhill skiing, camping, archery, reading fantasy novels, taking bad photos with old film cameras, using the Oxford comma, and playing the violin.
I am combining information from modern observational data, palaeoclimate proxy data, and climate model simulations to better understand the dynamics and characteristics of Australian drought and fire weather extremes.

Reconstructing changes in the strength in the Pacific Walker Circulation during the past 800 years, using a recently compiled
database of water isotope proxy records. I also used globally-distributed measurements of the stable isotopic composition of precipitation to investigate drivers of spatial and temporal variability in the global water cycle.
