I study the mobility of metals in the environment by adopting techniques in geochemistry, hydrogeology, and mineralogy. During my PhD I developed methods to trace molybdenum and zinc mobility in mine wastes through stable isotope analyses. This research was conducted at UBC's Pacific Centre for Isotopic and Geochemical Research with a multicollector ICP-MS instrument. I am currently working as a post-doctoral fellow in partnership with UBC and Lorax Environmental Services on a study of uranium and arsenic release into groundwater in the Dawson Range, Yukon. Advanced mineral exploration projects are present in this region, and a better understanding of metal release from the local geological formations into water has implications for water-quality management at eventual mine sites.
