I have 6+ years combined education and employment experience using geochemistry to answer a variety of questions relevant to academic research and the mining and mineral exploration sector. Currently, I work as a research assistant at the CarbMin Lab and part-time at the Pacific Centre for Isotopic and Geochemical Research.

My graduate and undergraduate research to date has primarily involved studying mafic layered intrusions (MLI). MLI are excellent natural laboratories for understanding important petrologic concepts, especially in closed-system intrusions where slow-cooling with little interaction can be achieved.

My MSc project investigated the geochemical compositions of plagioclase and alkali feldspar in the Skaergaard intrusion using two complementary microanalytical approaches: (1) major and minor element characterization by electron microprobe and (2) Pb isotope compositions by LA-ICP-MS. The combined results provide new insights on the crystallization history of the Skaergaard intrusion, the extent of modification of mantle-derived melts in the crust during flood basalt magmatism, and the role of the Skaergaard intrusion in the evolution of the North Atlantic Igneous Province. My thesis can be downloaded here.
