My research interests are very broad, in that I am an environmental geochemist/biogeochemist interested in aquatic, soil and dust geochemistry in the context of both ecological habitat and biogeography and climate change. I was a member of the McMurdo Dry Valleys Long-term Ecological Research team for 24 years and was the lead-PI for ~8 years. In this capacity my group's focus was on the geochemistry of both lakes and streams in these valleys. This work included documenting the history of the lakes as it related to changing climate, the source of solutes to the lakes, and the quantification of chemical weathering in the streams, among other issues. More recently I have been interested in the geochemistry of soils in the TransAntarctic Mountains, the biogeochemistry of of subglacial environments, and the subaerial flux of iron from glacier melt into the Southern Ocean.
