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.
