Research
I am interested in using original field observations of sedimentary rocks paired with a range of geochemical proxies to explore key Earth history events. I am particularly fascinated by ancient glaciations and large perturbations to the global carbon cycle that punctuate the Neoproterozoic and Paleozoic Eras. Using samples spanning the end-Ordovician Hirnantian glaciation, my current research investigates how geochemical and isotopic signatures are incorporated and altered within carbonate rocks at the micron-scale, using secondary ion mass spectrometry. This work aims to decipher spatial variability of 34S at a scale previously unobtainable, thereby eliminating much of the uncertainty of chemostratigraphic records generated using bulk samples.
