About
Prof. Paul Halloran is an Associate Professor in Ocean and Climate science within the Collage of Life and
Environmental Sciences at the University of Exeter,
where he moved in 2013. Our growing research group is focused
on the role of the oceans within climate change, with a focus
on biogeochemical cycling, variability and predictability.
The group builds on Paul's multi-disciplinary background to
tackle questions pertaining to climate change and its impacts
on society in novel ways. Paul’s degree and PhD were in the
Department of Earth Sciences in Oxford, where working with Prof. Ros
Rickaby, he examined ENSO change over the Pliocene,
developed novel geochemical climate proxy techniques, and
investigated the impact of ocean acidification on calcifying
phytoplankton. After his PhD Paul moved to the Met
Office
Hadley
Centre as a scientist, then senior scientist in ocean
biogeochemical modeling. In the Hadley Centre Paul was heavily
involved in the development, validation and application of the
Earth System Model HadGEM2-ES. Working with this model, Paul
and colleagues investigated the mechanisms behind novel
biogeochemical climate feedbacks, the role of anthropogenic
aerosols in recent climate change, reversibility in the earth
system and more.
