Our group's research bridges the fields of oceanography, biogeochemistry, and sedimentary geology, with the goal of understanding the relationship between the marine carbon cycle and climate change. More specifically, we investigate how changes in ocean deoxygenation, land to sea delivery of carbon and nutrients, and benthic-pelagic biogeochemical coupling control changes in the production and preservation of organic carbon. Our interdisciplinary approach combines seagoing science, geological fieldwork, and multi-proxy geochemical analyses to advance my overall goal of understanding and predicting the impact of anthropogenic climate change on marine biogeochemical cycles by combining modern process-focused studies with reconstructions of past marine biogeochemical cycling from the sedimentary record. A key aspect of this work includes involvement in the international scientific ocean drilling community.
