Marine Microbial Macroecology Lab

Rosie Sheward


My main interest is in the evolution of coccolithophores (unicellular, calcite-producting phytoplankton). My research combines the study of both extinct and living phytoplankton to establish direct links between fossilized phytoplankton remains and present-day species and communities, bringing together approaches and datasets from the traditionally separate fields of phycology and micropaleontology.

I am presently investigating cellular stoichiometry and macromolecular composition in coccolithophores. This contributes to the wider research of lab members into the interactions between cellular resource requirements, resource availability, competitive species interactions, and biogeochemical cycles that ultimately drive the evolution of phytoplankton communities under climate change.
