Introduction
My research focuses on ice core geochemistry, trace metal geochemistry, and environmental chemistry. I am interested in using environmental archives to trace natural and anthropogenic sources of heavy metals. I work in a diverse array of systems from West Coast estuaries to Arctic environments, developing and applying high-resolution geochemical techniques. Currently, I am using lead isotopes in glacial ice to fingerprint historical (500 BCE to the present) changes in lead pollution sources.

Ice cores can provide high-resolution records of anthropogenic activities, observable in gas and impurity records, for at least the last few millennia. Such archives demonstrate the ubiquity of human influence and the importance of legislation in mitigating these impacts.
Emissions from mid-latitude industrial activities (e.g., mining, smelting, coal combustion) result in long-range atmospheric transport of lead (Pb) to the Arctic. While previous measurements of elemental concentrations and Pb isotopic ratios in ice and sediments have been used to suggest potential sources of toxic heavy metal pollution in these reg...
