My interests lie in environmental monitoring and the implications of contaminants on human health and conservation. As such, I study how elements and isotopes can be used as tracers in the environment by collecting organisms or their byproducts as a means of sampling different regions and time periods. I primarily measure metals and lead (Pb) isotopes in biomonitors such as, bees/honey, Pacific salmon, and bowhead whales. By sampling organisms in the environment, I can acquire large sample sizes that represent the environment at various points in time that represent facets of larger biogeochemical systems. Laboratory and analytical work is done at the Pacific Centre for Geochemical and Isotopic Research using Quadrople ICP-MS and MC/HR-ICP-MS.
