Brooke Hoppstock-Mattson

PhD Geological Sciences


My interests lie in environmental monitoring and the implications of contaminants on human health and conservation. As such, I study how elemental concentrations 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 metal concentrations and lead (Pb) isotope ratios in biomonitors such as, bees/honey (Apis mellifera), chum salmon (Oncorhynchus keta), and bowhead whales (Balaena mysticetus). By sampling organisms, I can acquire large sample sizes that represent the environment at various points in time that represent facets of larger biogeochemical systems. I am passionate about developing and refining innovative geochemical tools, such as this. Laboratory and analytical work is done at the Pacific Centre for Geochemical and Isotopic Research using Quadrople ICP-MS and MC/HR-ICP-MS.
