Dr Fiona O'Connor

Senior Lecturer in Atmospheric Composition


Fiona joined Exeter University as a Senior Lecturer on a part-time basis in October 2022, and for her remaining time is a Research Fellow at the UK Met Office. In her Met Office role, Fiona leads a team of scientists and scientific software engineers and her key areas of interest include climate forcing, climate feedbacks, climate change mitigation, and air quality. She was the principal developer of the United Kingdom Chemistry and Aerosol (UKCA) model for its inclusion in the UK’s HadGEM2 Earth System Model. She also contributed to the development of UKESM1 (add link) and led the UK contribution to the Aerosol and Chemistry Model Intercomparison Project (AerChemMIP). She is currently co-lead of the ozone radiative forcing working group for the Tropospheric Ozone Assessment Report and sits on the scientific steering committee of the CACTI initiative on atmospheric composition and climate.

Fiona has won research grants of up to £1.5M, including awards for a number of EU projects (CRESCENDO, ESM2025) as well as grants from the Natural Environment Research Council (NERC) and the UK’s Joint Weather and Climate Research Programme (JWCRP). Modelling work that Fiona has performed includes assessment of the climate forcing from anthropogenic activities, modelling the methane cycle, and an assessment of the role of methane mitigation and removal on climate and air quality. Fiona has published over 100 peer-reviewed articles in the scientific literature, including publications in Nature, Nature Communications, npj Climate and Atmospheric Science, and Reviews of Geophysics. She has received a number of national commendations and awards for her work. Fiona was a contributing author for the IPCC 5th Assessment Report and a reviewer of the 6th Assessment Report.
