My work focusses on understanding the response of marine phytoplankton to environmental change and the subsequent ecological and biogeochemical impacts.
In my current position within the OceanBug group, I employ shotgun proteomic analysis to examine the effects of ocean warming on the cellular functioning of key taxonomic groups of phytoplankton and their use of metal-binding proteins, as well as to identify proteins/biochemical pathways associated with intracellular calcification in coccolithophores.
Through my PhD and Master’s research I examined the impact of emerging marine pollutants, nanomaterials and microplastics, on the fitness and functioning of marine planktonic organisms.
