Navigating the New Arctic Project (NNA)
I am part of an NSF-funded collaborative project that holistically examines the impacts of riverbank erosion in the Yukon River Basin, Alaska. My research focuses on mercury biogeochemistry and transport, investigating how shifting landscapes influence mercury cycling in Arctic freshwater systems.

Rapid Arctic warming threatens to destabilize mercury (Hg) stored in permafrost soils, yet current estimates of these Hg stocks vary by nearly fourfold. The pathways and extent of Hg release as permafrost thaws remain poorly understood, posing risks to water quality, human health, and ecosystems. Using sediment samples and remote sensing, we quantify Arctic mercury stocks and investigate their transport through river systems.
