The University of British Columbia

Research Interests and Duties

I am part of the research team in PCIGR, and am involved in several aspects of the group. I am primarily involved in analysis and interpretation of lead isotopes in sulphides, for mineral deposit-related studies and isotopic tracer studies. I also run laser ablation ICPMS dating on zircon samples.

I am the Laboratory Coordinator for the Stable Isotope laboratory. I run the Delta Plus XL mass spectrometer, used for analysis of light stable isotopes in minerals, waters and gases (C, O, H).
