Biological and chemical oceanography, marine microbial ecology and biogeochemistry. My research focuses on the feedbacks between climate change and marine ecosystems. I am interested in both fieldwork and modeling. My field research combines microbial ecology and community structure with inorganic carbon chemistry. Recent projects include investigating climate-active gas emissions from Antarctic sea ice communities, bacterial remineralization in the Amundsen and Ross Sea polynyas, and carbon sequestration by microbial communities in the Amazon River plume.
