About
Paul Halloran is a Senior Lecturer in Geography, 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.
