Pierre specialises in plankton ecology, statistical analysis and data processing. His research is focused on developing and using ecological concepts to explain spatio-temporal variability in planktonic communities. He has published papers dealing with ecological niche concepts, marine pelagic biodiversity, global change, biogeography, mesoscale ecology and spatial and temporal scales. As well as contributing to the blue sky research, he is involved in a large number of contracts and has extensive experience in producing scientific reports. Pierre has recently been involved with the NERC Consortium Marine Ecosystems Research programme (MERP), NERC Quantifying links between human influences on climate, shifting seasons and widespread ecosystem consequences, H2020 Optimising and Enhancing the Integrated Atlantic Ocean Observing Systems (AtlantOS) and INSITE Influence of Man-Made Structures in the ecosystem: is there a planktonic signal?
