MSc graduate
University of Toronto

I completed my undergraduate degree in Geological Sciences from Queen’s University in Kingston, Ontario in 2010. Since graduating I have been working in the gold exploration and mining industry in Canada and in Myanmar, giving me 4+ years industry experience as an economic (exploration and mine) geologist.

My academic history in geochemistry began in the last two years of my undergraduate degree. I worked during the summer at Western University in London, Ontario as a field and research assistant in the Laboratory of Stable Isotope Science. I researched clays and conducted x-ray diffraction analysis of their lattice structure which was later published in the journal Geology (John et al. 2012). The following summer (2009), I was given funds from the Canadian Space Agency and NSERC to design my own undergraduate thesis project. This project let me combine my interests in field work, geochemistry, and ore geology to study Archaean hydrothermal systems. My undergraduate thesis work included field mapping and map digitization, petrographic analysis, stable oxygen isotope analysis, and geochemistry and rare earth element analysis.

My passion for ore deposits, hydrothermal fluids, as well as the Precambrian era, led to the formation of my MSc project. I am working with Barbara Sherwood Lollar’s lab studying fluid inclusions within Precambrian rocks from the Kidd Creek mine. The goal is to study the fluid paragenesis of the ore-forming hydrothermal system and to analyze volatile fluid inclusions for their composition as well as their carbon isotopes.
