Dr Georgy Falster
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.
My research explores long-term (decadal & upward) hydroclimate variability, from regional to global scales. I use stable water isotope geochemistry and information from earth system models, as well as various types of palaeoclimate proxy data from multiple archives including
- lake & marine sediments
- glacier ice
- corals & other marine carbonates
- terrestrial & marine molluscs
- tree rings
- speleothems (cave carbonate)
I am particularly interested in climate variability through the Common Era (from the year 0 CE to present). I use modern observational data to inform our understanding of pre-industrial climate variability, but also use Common Era palaeoclimate data to better understand low-frequency climate variability, which can inform model simulations of earth's current and future climates.
