Reconstruction of monsoon dynamics during the late Quaternary using speleothem data and model simulations.

The oxygen isotopic composition of secondary carbonate cave deposits (speleothems) are widely used to investigate past monsoon variability. My research project utilises the SISAL (Speleothem Isotopes Synthesis and Analysis) database, which has compiled more than 650 oxygen and carbon isotope speleothem records, to investigate past monsoon variability at the regional and global-scale. To interpret these spatio-temporal trends in terms of changes in monsoon climate, I compare speleothem oxygen isotope trends with model simulations of past climate. This research is funded by the ERC-funded project GC2.0 (Global Change 2.0: Unlocking the past for a clearer future).


About Me:

I have a Master of Geology and Bachelor of Science (MGeol, First Class Hons) degree in Geological Sciences from the University of Leeds, which incorporated a study year abroad to Victoria University of Wellington, New Zealand. During my undergraduate, I completed a year-long research project where I investigated carbon sequestration into Arctic marine sediments, utilising geochemical and isotopic sensors. As a PhD student, I work alongside palaeoclimate scientists, modellers and statisticians as part of the SPECIAL research group ( to reconstruct and better understand past changes in climate and environment.
