Research Statement

My research is focused on terrestrial and aquatic processes that influence the recovery of subarctic lakes impacted by mining pollution. We use a variety of techniques across the disciplines of hydrology, biogeochemistry and limnology to measure fluxes of contaminants (mostly arsenic and antimony) within subarctic watersheds. These types of information are useful so that we can better predict the long-term fate of contaminants in northern environments.  I have 15 years of experience as a northern-based scientist and much of this work has been in collaboration with local communities, government agencies, and universities.
