Research Interests

I'm fascinated by the role of freshwater in the Polar ocean carbon cycle. I use different types of geochemical tracers to determine freshwater sources and pathways in the marine system, in particular along the coasts where river inputs directly intersect areas of sea ice melt. My research questions bridge the earth and ocean sciences - following carbon sources, trajectories, and transformation along the land-ice-ocean continuum. My recent focus has been on the Kitikmeot region of the southern Canadian Arctic Archipelago and I am currently working with partners in Nunavut to conduct year-round monitoring in local river and coastal systems.
