I am currently a PhD student at the University of Victoria in the department of Earth and Ocean Sciences. I received my honours BSc in Earth Sciences from UVic, and am now studying Neoproterozoic Earth History in the Ediacaran (~635-541Ma). Broadly, I am interested in biogeochemical data and understanding early paleoclimatic events and early carbon cycle dynamics in the Precambrian. In my time as an undergrad, I completed my Honours thesis studying carbon cycle dynamics in the Mesozoic (specifically the Triassic-Jurassic interval). Using stable isotopes of carbon, oxygen as well as calcium and magnesium, it is possible to assess these changes in carbon cycling. The determination of diagenesis (localized alteration) in these marine carbonates is essential in understanding the origins of isotopic excursions. An isotopic excursion is a deviation from a geochemical homeostasis, and during the Neoproterozoic, these excursion events are extraordinarily prevalent. My research at UVic aims to attempt to understand some of these excursions. The Shuram-Wonoka Anomaly is the most negative carbon isotopic excursion in Earth history and is possibly found within the Rocky Mountian carbonate outcrops in western Canada. By studying the Miette group of British Columbia and Alberta, I hope to capture this extremely negative carbon isotopic anomaly and assess possible causes and origins of it. My research primarily focusses on both platformal and deep-basin carbonate successions comprising vast breccia units that are tested via isotope conglomerate tests (ICTs) which are used to assess the primary nature of these excursions and the presence of local diagenesis.
