Characterizing cobalamin cycling by Antarctic marine microbes across multiple scales
… two keystone phytoplankton types: diatoms and Phaeocystis antarctica. This thesis investigates microbe-driven cobalamin cycling in Antarctic seas across multiple spatiotemporal scales. I conducted laboratory culture experiments with complementary proteomics and transcriptomics to investigate …

Feeding, Dark Survival, and Foreign Organelle Retention in an Antarctic Dinoflagellate
… dinoflagellate isolated from the Ross Sea, Antarctica (RSD) retains plastids from its haptophyte prey Phaeocystis antarctica. It is a member of the Kareniaceae, a dinoflagellate family whose other members all contain permanent tertiary plastids of haptophyte origin. A subset of its cells …

Phytoplankton's role in the biological pump during the growth season across the Atlantic Southern Ocean
… Here, the phytoplankton community shifted from Phaeocystis Antarctica- to diatom-dominated as the growth season progressed, coincident with an increase in upper water-column stratification. This shift may have further decreased carbon export as P. Antarctica can fix up to 50% more carbon per …
